INFORMATION

BULLETIN

NUMBER: 02-1

MODELS: Vent-Free Log Sets

PURPOSE: This is a general information bulletin written to insure the proper installation, application, and use of vent-free log sets.
There are many factors that come into play when there is an occurrence of sooting with any log set. We have compiled the following
informtion to cover any potential issue that can create sooting. Preventative measures taken before initial start up can avoid future
issues with log sets.

IMPORTANT INSTALLATION GUIDELINES

Proper Log Placement
Log placement is critical to proper burner performance. Logs must
be correctly positioned onto the burner. The photos in this manual
show the proper pinned position for logs on this set. Owners need to
be shown proper log placement and instructed not to move the logs.

Logs must t rmly onto the burner when positioned as shown in the

photos. Misformed logs or logs with sloppy holes must be replaced.

Proper Placement of Rock Wool and Decorative Lava Rock
Rock wool can be added to burners for a glowing ember effect. It
must be positioned only on the front portion of the burner. The
photos in this manual show the proper placement of rock wool.
Decorative lava rock or small wood pieces should never be placed

on the burner. These items are only for placement on the oor of the
replace or rebox.

Proper Primary Airow into Burner
For proper burner operation and ame appearance , the ow of

primary air into the venturi tube, located on the rear of the burner,

must not be reduced. This ow of air is reduced if dirt, lint or other

obstructions build-up around or inside the venturi. Any obstruction

in the venturi tube area must be removed. The ow of air into the
venturi is also reduced if the gas orice isn’t centered in the venturi

inlet and/or is not aligned with the venturi. Any misalignment of the

burner orice may be corrected by bending the shutter cap holding
the orice to the inlet of the venturi tube.

Ceiling Fans, Portable Fans or Logs Installed Near Cold Air Returns

Ceiling fans or oscillating oor type fans need to be monitored

during the operation of vent-free logs. If the air blows directly into

the ame causing it to impinge on the log set, or rebox, it should be

turned off or redirected. Ceiling fans could be

reversed to possibly eliminate ame impingement, and the oor

fan could be redirected. Upon installation, be aware of any cold air
returns or vents in the proximity of the log set. Any draft created

around a vent-free log set can cause the ame to impinge on the log

and create a sooting situation.

Candles
Avoid the use of scented or decorative candles while the log set
is in operation. Candles produce a residue in the air that creates a
soot like substance. Burning candles while the log set is operating

magnies the problem. It should be noted that candles, in general

produce soot. The amount of time burned and the quantity of
candles burned will determine the amount of soot produced and
deposited.

Make Owners Aware of Proper Log Set Operation
Properly installed and properly maintained log sets do not deposit
soot on the logs. If users see soot appear on a log, call for service.
Do not continue to operate the log set.

Sunken Fireplace

If installing this unit into a sunken replace, you must raise the oor
to insure adequate airow and guard against sooting. Raise replace
oor using a non-combustible material, which is secure.

Glass Doors
Make sure that glass doors are open during all operations of the
logset. The opening of the glass door frame should be the dimension

used for the minumum front opening of the rebox.

Woodburning Fireplaces

The interior of the rebox and the chimney should be cleared and

free of all creosote before installing a gas burning log set. Creosote
will soften when heated and can drop on the log set casuing odors
and possible sooting.

PILOT FLAME CHARACTERISTICS

Figures 1 and 4 show a correct pilot ame pattern. The correct
ame will be blue and will extend beyond the thermocouple. The
ame will surround the thermocouple just below the tip. A slight
yellow ame may occur where the pilot ame and main burner
ame meet. Figures 2 and 5 show an incorrect pilot ame pattern.
The incorrect pilot ame is not touching the thermocouple. This

will cause the thermocouple to cool. When the thermocouple cools,
the heater will shut down.

VFSR PILOT

2. Blow air pressure through the holes indicated by the arrows.
This will blow out foreign materials such as dust, lint and spider
webs. Tighten nut B also by grasping nut A.

Sect1:13

PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR

This heater shall not be installed in a conned space unless provisions are

provided for adequate combustion and ventilation air.

The National Fuel Gas Code denes a conned space as a space whose

volume is less than 50 cubic feet per 1,000 Btu per hour (4.8m3 per kw) of
the aggregate input rating of all appliances installed in that space and an

unconned space as a space whose volume is not less than 50 cubic feet

per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all
appliances installed in that space. Rooms communicating directly with the
space in which the appliances are installed, through openings not furnished

with doors, are considered a part of the unconned space.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh
air for combustion and ventilation. However, in buildings of unusually
tight construction, you must provide additional fresh air.

Unusually tight construction is dened as construction where:

a. Walls and ceilings exposed to the outside atmosphere have a con-

tinuous water vapor retarder with a rating of one perm or less with
openings gasketed or sealed, and

b. Weatherstripping has been added on openable windows and doors,

and

c. Caulking or sealants are applied to areas such as joints around

window and door frames, between sole plates and oors, between
wall-ceiling joints, between wall panels, at penetrations for plumb-

ing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide

additional fresh air.

Warning: If the area in which the heater may be operated is smaller than

that dened as an unconned space or if the building is of unusually tight

construction, provide adequate combustion and ventilation air by one of
the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA
54, Air for Combustion and Ventilation, or applicable local codes.

The following formula can be used to determine the maximum heater

rating per the denition of unconned space:

If the area in which the heater may be operated is smaller than that dened
as an unconned space, provide adequate combustion and ventilation air

by one of the methods described in the National Fuel Gas Code, ANSI
Z223.1, NFPA54.

Adhere to all codes, or in their absence, the latest edition of THE
NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA54 which can be

heater. Left and right clearances are determined when facing the
front of the heater.

Glass Doors

Make sure that glass doors are open during all operations of
the logset. The opening of the glass door frame should be the

dimension used for the minimum front opening of the rebox.

Follow these instructions to ensure safe installation.

Failure to follow instructions
exactly can create a

re hazard.

CLEANING AND SERVICING

Annual inspection and cleaning by your dealer or qualied

service technician is recommended to prevent malfunction

and/or sooting.

TURN OFF HEATER AND ALLOW TO COOL BEFORE
CLEANING.

Remove logs, handling carefully by holding gently at each end.
Gloves are recommended to prevent skin irritation from ceramic

bers. If skin becomes irritated, wash gently with soap and water.

Refer to manual for correct log placement.

PERIODIC CLEANING – Refer to parts diagram for location
of items discussed below.

• Do not use cleaning uid to clean logs or any part of heater.

• Logs - brush with soft bristle brush or vacuum with brush

attachment.

• Remove loose particles and dust from the burner areas,

controls, piezo covers and grate. Don’t remove crushed media
from inside burner box.

• Inspect and clean burner air intake holes. Remove lint or

particles with brush. Failure to keep air intake holes clean will
result in sooting and poor combustion.

Warning:
Never use needles, wires, or similar cylindrical objects to

clean the pilot to avoid damaging the calibrated ruby that

controls the gas ow.

Figure 6

ANNUAL CLEANING/INSPECTION – Refer to parts diagram
for location of items discussed below.

• Inspect and clean rear burner air intake holes. Remove lint or

particles with vacuum or brush. Failure to keep air intake

holes clean will result in sooting and poor combustion.

• Inspect and clean all burner ports.

• Inspect ODS pilot for operation and accumulation of lint at air

intake holes.

• Verify ame pattern and log placement for proper operation.

• Verify smooth and responsive ignition of main burner.

• Check level of glass media in burner. Burner should be full,

up to the level of openings in burner top.

Attention: Ceramic media that is dislodged from burner box
during shipment can be replaced through openings in burner
top. If settling of ceramic media occurs during shipment an
additional bag of ceramic media, part number, 12389 can be
ordered from Empire Comfort Systems, Inc.

Sect1:15

PLACEMENT OF GLOWING EMBERS AND LAVA ROCK

Placement of the glowing embers (rock wool) is very individual
and light coverage will provide your best effects. We recommend
separation of the rock wool by hand and make your coverage as

light and uffy as possible.

Place just enough embers on the burner to obtain the glow and a
gold, yellow ame.

Do not place embers (rock wool) over large ports in rear portion
of burner.

Rock wool should not be placed in the area of the pilot assembly.

Replacement of loose material (glowing embers) must be purchased
from Empire Comfort Systems, Inc. Application of excess loose
material (glowing embers) may adversely affect performance of
the heater. WARNING: All previously applied loose material must
be removed prior to reapplication.

Refer to Parts List in owners manual to order loose material (rock
wool).

Placing Lava Rock in Front of Burner on Fireplace Floor

Spread lava rocks on replace oor in front of the burner pan.

The lava rocks are for decorative effect and are not required for

replace operation.

ATTENTION: DO NOT PLACE LAVA ROCKS ON BURN­ER, LOGS OR ROCK WOOL. THE LAVA ROCKS SHOULD
ONLY BE PLACED ON THE FIREPLACE FLOOR.

FIREPLACE PREPARATION

• Turn off gas supply to replace or rebox.

• Have the replace oor and chimney professionally cleaned to remove

ashes, soot, creosote or other obstructions.

Have this cleaning performed annually after installation.

• Seal any fresh air vents or ash clean-out doors located on oor or wall
of replace. If not, drafting may cause pilot

outage or sooting. Use a heat-resistant sealant. Do not seal chimney

ue damper.

Install and operate the appliance as directed in this manual.

Converting ue take-off to rear venting

When switching out the ue and inlet vent collars to run horizontally

off the rear vent, the following steps must be taken.

1. Remove the inlet vent collar (8 screws) and ue collar (4 screws)
from the top of the replace, and set to the side.

2. Remove the inlet cover plate and ue cover plate located on the
back of the replace. These will be used to close the top ue

and inlet openings.

3. Insert the insulation retainer bracket and insulation into the top

ue pipe before reinstalling the ue cover plate over the top ue

with 4 screws.

4. Reinstall the inlet cover plate over the top inlet opening with 4

Installing Vent Components (Figure 18)

Begin the vent system installation by installing the rst Simpson

Duravent component, 90° elbow to the starting collars or straight
pipe on the top of the appliance, then the straight pipe length and
then horizontal or vertical termination kit.

NOTE: All outer connection joints must be sealed with aluminum
tape, screws or silicone sealant rated above 300°F/149°C. The
inner ue joints do not require any sealant.

Simpson Duravent vent system components lock into place by
sliding the concentric pipe section with four (4) equally spaced
interior beads onto the appliance collar or previously installed
component end with four (4) equally spaced indented sections.
When the internal beads of each starting outer pipe line up, rotate
pipe section clockwise 90° (approximately 3 inches). The vent pipe
is now locked together.

Continue adding components per the pre-planned vent system

conguration. Be certain that each succeeding vent component
is securely tted and locked into the preceding component in the

vent system.

TERMINATION CLEARANCES

Termination clearance for buildings with combustible and noncombustible exteriors.

Vertical Sidewall Installations

Important! Minimum clearance between vent pipes and combustible materials is three (3") (76mm) on top, and (1") (25mm) on bottom
and sides.

Important! When vent termination exits through foundation less than 20" below siding outcrop, the vent pipe must extend outward so

that the horizontal vent terminal is located ush to, or beyond the outcrop siding.

Information on Various Venting Routes and Components
Important: It is always best to locate the replace in such a way that minimizes the number of offsets and horizontal vent length.

Since it is very important that the venting system maintain its balance between the combustion air intake and the ue gas exhaust, certain
limitations as to vent congurations apply and must be strictly adhered to.

The graph showing the relationship between vertical and horizontal side wall venting will help to determine the various vent lengths
allowable.

The horizontal vent run refers to the total length of vent pipe from the ue collar of the replace to the face of the outer wall.

The maximum horizontal vent run is 20 feet (457 cm) when the vertical vent rise is 8 feet (244 cm).

Venting terminals shall not be recessed into wall or siding.

ance to a chimney ue servicing a separate solid fuel-burning appliance.

WARNING

Failure to follow these instructions may create a possible re hazard and will void the warranty.

WARNING

Always maintain minimum clearances around vent systems. The minimum clearance to combustibles for horizontal runs of vent pipe

is 3 inches from the top, and 1 inch from the sides and bottom of the vent system. Do not pack the open air spaces around the replace
or ue with insulation or other materials. Any horizontal run must have a 1/4” rise for every one (1) foot of run towards the vent ter-

mination. The vent above the roof must terminate vertically.

WARNING

Contact your Local Building and Fire Ofcials about restrictions and installation inspections in your area.

IMPORTANT SAFETY INFORMATION

• The vertical termination cap MUST be vented directly to the

outside. The termination kit MUST NEVER be connected to
a chimney ue(s) servicing a separate solid-fuel burning ap­pliance or any other appliances.

• Termination cap MUST NOT be mounted horizontally.

• The exible vent pipe cannot be intermingled with any of the

rigid vent pipe section(s). DO NOT connect two sections of

exible vent pipe together to achieve a longer length without

the use of approved connectors.

• The installation must conform with local codes or in the ab-

sence of local codes, with the National Fuel Gas Code, ANSI
Z223.1 (in the United States) or with the current installation
code CAN/CGA B149 (in Canada).

• Only Direct Vent replaces approved for use with Empire

Step-By-Step Installation For Flex DV Kit

1. Unpack vent components and check all items for shipping
damage.

2. For this venting system to operate as designed it is depen­dent on the use of all parts and procedures detailed in these
instructions. Failure to follow these instructions may poten­tially affect the performance of this vent system and the at­tached appliance.

3. As per the replace manufacturer’s instructions, replace the
existing 6 5/8” diameter replace vent adapter with the 7”
diameter ex vent replace adapter included in the vent kit.

Install the adapter collar with the screws removed from the
standard replace collar. Refer to the replace manual for ad­ditional information on the vent collar removal and installa­tion.

4. Once the replace location has been determined, mark the
ceiling where the ex vent will pass through. Cut an opening
for installation of the restop thimble assembly. The open­ing must measure a minimum of 9-1/2” x 9-1/2” square. See

Figure 21.

5. Next, determine the location for the cutout in the roof open­ing. This opening must be large enough to provide a mini-

mum 1” air space clearance from the vertical vent pipe to any

combustible framing.

6. Install the Firestop/Thimble assembly to the framed opening
in the ceiling using common nails or screws.

Note: The thimble assembly is adjustable up or down as
needed within the restop. It is also designed with a pivoting
restop for use with 0 - 3/12 pitch cathedral ceilings.

7. To begin vent system assembly, rst layout all the vent com­ponents on the oor in the order in which they will be as-

sembled.

8. Stretch the 4” diameter inner ex ue and 7” diameter outer
ex vent to the maximum length of 6 feet.

9. Install the spring spacers provided around the 4” diameter
ex ue at 1 foot intervals, then slide the ue pipe with spac­ers into the 7” diameter outer ex vent pipe. Make sure the
springs are spaced evenly starting at 12 inches from the re-

place collar. See Figure 22.

components laid out on the oor, begin securing these parts

together. First, apply a generous bead of silicone sealant to

the inside of the 4” diameter ex ue (not the end with the
pre-installaed connector), then slide the ex ue over the 4”
diameter hard pipe ue. Be sure to overlap at least 1-1/4”. Se­cure this connection with a 4” diameter band clamp provided.
Be careful not to damage or tear the ex ue when tightening

clamp.

11. Repeat the connection process for the outer 7” diameter ex
vent to hard pipe connection. Use silicone sealant at this joint
also, overlap at least 1-1/4”, then secure the joint with the 7”

diameter band clamp provided. Be careful not to damage or

tear the ex vent pipe when tightening the clamp.

12. While the venting is still on the oor, assemble the roof jack

components as shown in Figure 23 and pre-install the roof

jack assembly to the hard pipe approximately 18” from the

top end of the hard pipe.

13. Now the pre-assembled vent system may be carried to the
roof, then lowered through the roof cutout opening (see step

5). Feed the ex vent end down through the roof opening and
restop/thimble assembly installed in steps 4 through 6.

14. Secure the roof support assembly to the roof sheathing with
at least (4) nails/screws through each support bracket. Check
that the combustible clearances through the roof framing will

maintain at least a 1” clearance from the vent pipe.

15. Determine how high the vent terminal should be located
above the roof line based on the roof pitch information shown

in Figure 24. Adjust the vent system height by loosening the

pre-installed roof support pipe clamp and sliding the vent
pipe up or down as pre-determined, then re-tighten the pipe
clamp. Install a couple of sheet metal screws through the pipe
clamp into the outer hard vent pipe to lock in place.

16. Check to make sure that the bottom end of the ex vent is
long enough to reach the replace adapter collars. If too long,
trim off the extra ex vent not needed.

17. To attach the vent connections at the replace, be sure the 7”

diameter adapter collar has been installed per step 3. Apply

a bead of silicone sealant to the 4” diameter ex connector,
then slide the ex pipe adapter collar into the replace ue

collar and secure by installing a minimum of two (2) screws

through the ue collar and into the adapter. See Figure 25.

18. Apply sealant to the 7” diameter adapter collar, slide outer
ex vent over the collar, then secure with a 7” diameter band

clamp. See Figure 25.

19. Once the lower connections are made and the ex pipe is

secured with support bands as required (3 feet minimum be-

tween supports) then the roof ashing can be installed. See

Figure 26.

20. Install the roof ashing, and seal using common construc­tions practices.

21. An additional storm collar band is provided in kit that may be
used as an attic insulation shield. The collar can be installed

around the ex pipe (or hard pipe) just above the restop

thimble. This collar will act as a shield to prevent blown in­sulation from entering the thimble.

22. To complete the vent installation, install the vent termination

cap to the top of the hard vent pipe assembly. Mate up the ue

and outer telescopes with the hard pipe assembly, then secure
by installing a minimum of two (2) sheet metal screws into

the overlapped anges of the cap and pipe.

Parts Verication

See parts list on page 2:27 to verify components included in this vent
kit prior to installation.

NOTE: If installing onto wood, lap, or vinyl siding, the vinyl siding
kit should be used (sold separately, part number DV-822).

The vinyl siding vent kit, DV-822, is available from Empire Comfort

Systems, Inc. The depth is 3” (76mm), which enables the vent cap to
be extended away from vinyl siding or projections. The wall depth plus
the additional 3” (76mm) depth of the vinyl siding vent cap extension
should not exceed a total depth of 13 3/4” (349mm).

If wall depth exceeds 13 3/4” (349mm), extend system using
6 5/8” (168mm) x 4” (102mm) rigid venting (See Fireplace Instructions

for approved lengths) See Figure 29.

Installing Wall Thimble/Firestop Assembly

1. Fix replace to permanent location. If using rigid venting system,

install up to the location where it will exit the building.

2. Cut hole in wall for wall thimble/restop assembly (Figure 28)

into your combustible wall. Note: On brick or block exterior wall

a 7” (178mm) diameter hole needs to be cut.

Measure the total wall thickness to determine whether or not the

extension thimble is to be used. If the combustible wall depth is

over 5 3/8” (137mm), then the extension thimble should be used

(Figure 1).

3. Install the wall thimble assembly through the framed opening so

the restop plate is on the interior wall (Figure 28). Telescope
section should extend all the way through the exterior wall. Attach

with (4) 10 x 1” screws.

4. When placing the vent cap on an exterior wall covered with com­bustibles such as wood, lap, or vinyl siding, install the vinyl siding
kit to the exterior wall sheathing.

This is the most important part of the installation. With the

replace (and the rigid venting system if used) xed to its perma­nent location, the 6 5/8” (168mm) diameter air inlet tube and the
4” (102mm) diameter ue outlet tube are to be marked and cut

using the following procedure.

5. Attach the inlet tube to the outside mounting plate. Align
tinnerman clips on the tabs of the air inlet tube to the holes on

outside mounting plate, and x with (2) #10 x 1/2” screws.

6. With the vinyl siding kit installed to wall (if necessary), insert the 6

5/8” (168mm) diameter tube with outside mounting plate attached
through hole in wall. Connect to collar on replace or rigid vent

system. Measure between wall or vent cap extension and outside

DVVK-4RE VENT KIT INSTALLATION INSTRUCTIONS (continued)

Follow correct option according to venting method.

Connecting Directly to Fireplace

If the air inlet and ue outlet tubes are to be connected directly to

the unit (no rigid venting system is being used), then the gasket

provided must be used to seal the 4” (102mm) ue outlet tube.

Peel the paper off the self-adhesive gasket and then wrap it around
the end of the tube (if tube was cut, it is recommended to use cut
end) as shown in Figure 56. Pull the gasket tight at all times while
wrapping it around tube. The gasket ends should align, to form a
complete seal. The overlapped section should NOT come in con­tact with the seam in the tube. Apply high temperature sealant to
the opposite end of the tube (on the inside of the tube). The end
with the gasket will attach to the back of the unit. Continue with
Step 13.

DVVK-4F FLEX VENT INSTRUCTIONS

The DVVK-4F FLEX VENT KIT includes the following components:

• (1) Horizontal Termination Cap

• (1) 4-foot section of Flex vent with spacers (4" ue/7" outer

pipe)

• (1) 4" dia. Flue adapter collar

Flex venting can be installed either vertically or horizontally off of the DVP36 Series replaces. When installing a horizontal vent run from
top connections, maintain at least ½" rise for every 12" of vent run. When venting horizontal off the rear vent connections, allow a minimum
rise of 2". Refer to Figure 30 when mounting termination near vinyl siding.
CAUTION: Always stretch and secure venting with wire or metal strapping to ensure that the horizontal runs do not sag.
If space permits, it is generally easier to attach venting in the top vent conguration.
Because of sharp edges, always use gloves when handling the ex vent components.
Vent connections should overlap a minimum of 1" for proper sealing.
Always follow the general venting requirements for vent terminal location, vent lengths, and clearance to combustible materials.

INSTALLATION

1. Unpack vent components and check that all items are included.

2. Check to see that the vent spacer springs are located around the ue

vent at 8" and 12" intervals along its length. See Figure A. If not,
stretch the spacer springs to about 15" long and wrap them around

the ue, then interlock the ends of each spring about 2". See Figure

B. Maintain equal distance between spring spacers.

• (1) 7" dia. Outer Vent adapter collar

• (1) Wall Firestop/Thimble Assembly

• Hardware pack that includes band clamps and screws

7. If the venting is to long, trim off any excess vent before attaching
the vent end connectors.

8. Attach the Termination Cap to the outside of the house.

9. Prior to making the vent connections, apply high temperature
sealant (1000 degree F min.) to the vent connections before securing
with the band clamps provided. Note: the flue pipe end without the
adapter is to be installed to the Termination Cap.

10. Apply sealant to the outside of the flue pipe adapter and connect
to the flex flue pipe. Then insert the adapter into the fireplace flue.
Secure flue adapter to the fireplace flue with a minimum of two
screws provided. See Figure C.

11. Attach the Outer Vent pipe to the 7" dia. Collar on the fireplace with
a large band clamp provided. Sealant may also be used on the outer
vent connections.

12. Check all vent connections for tightness. Make sure horizontal
venting has the proper rise and combustible clearances required.
Refer to venting charts in fireplace instruction manual.

3.

Remove the 6-⅝" dia. Vent collar from the fireplace. Replace this

4. Slide the Flex Vent flue pipe into the Outer Flex Vent pipe.

Conrm 24Vac at “PV” and PV/MV” on ignition control module. If no, replace

the ignition control.

Check if pilot line and pilot orice are plugged. Clean or replace if necessary.
Adjust pilot ame if neccessary.

Conrm that the igniter is sparking at the pilot assembly when the “ON/OFF”

switch is activated. If not, undertake the following steps:

With “ON/OFF” switch “OFF”, remove wire at “TR” terminal at the ignition
control module. Disconnect the electrode wire “IGN” at the ignition control.
Connect one end of a jumper wire to the metal blade of a small screwdriver. At­tach the other end of the jumper wire to any metal part of the chassis. Reconnect
the “TR” terminal. Position end of metal blade approximately 1/8-inch from the
“IGN” terminal. Activate the “ON/OFF” switch. Sparking should occur, the

ignition control module is OK. Check if the electrode wire of the igniter is faulty.
If faulty, the pilot and electrode assembly should be replaced.

the receptacle (hot side) to split receptacle. This will be required
to separate blower and valve circuits.

2. Power for switched and live sides of Duplex Receptacle must
come from the same power source. (One circuit breaker on main
panel must switch all power off.)

3. From the wall box to the replace a 3-wire conductor with

ground is recommended, however (2) two-wire conductors
with grounds may be used in place of a 3-wire conductor with
a ground if the black wires from the thermostat and blower

switch are identied.

4. Two wall switches, or a wall switch and thermostat may be used
to activate the two receptacle plugs independently.

RF STANDING PILOT OPERATING INSTRUCTIONS

Features Benets

• Self powered millivolt receiver/valve • No external power or batteries required to operate valve and flame modulation

• Thermostat performance • Flame cycles and modulates such that heat output equals heat loss from the room

• Auto mode • Flame & fan are controlled automatically

• Self powered millivolt control • No external power required to control gas valve and flame modulation

• Integrated Valve Electronics • No electronics, rheostat, or limit installation required

• Failure analysis • Troubleshooting with information from LED

• Pilotstat interlock • When valve is turned off, power unit must drop out before pilot can be relit

• F or C temperature units • Display local temperature units

Please review and retain the instructions included with the RF Transmitter. It provides additional information and details
concerning the operational procedures and functions for the RF Remote Control.

Functions

• Flame powered system

• Flame powered ame modulation

• Electronics integrated into valve to provide thermostat, ame, and fan functions with RF commands

• Temperature compensated RF receiver

• Main burner goes to "high" when manual switch is set on "local"

• Fan powered by 120 vac

Transmitter Signal

• When the transmitter is in the Auto mode, a signal is sent every 10 minutes if there is a change in the room temperature

• When the transmitter is in the On or Off modes, a signal is also sent every 10 minutes with the status of On or Off condition

• The transmitter will work at a minimum of 25 feet from the receiver

• Make sure antennae is not touching metal and is horizontal. Refer to Figure 36.

Receiver Shutdown of Burner

• In the remote, auto mode the valve shuts off if it does not receive a signal within 3 hours from the transmitter

• In the local mode the valve does not shut off

• In the remote, manual mode the valve shuts off if it does not receive a signal within 6 hours from the transmitter

Thermopiles

• The negative leads (white) must be connected to the terminals with the one white dot marked next to them

• Each thermopile must provide at least 500 mV open circuit voltage

• If output is erratic, check thermopile for intermittent shorts

Note: In normal operation, LED blinks once every two seconds; also, LED will be on for one second after every valid command
received by the RV8310D; these are not error codes.

Failure codes (see Table) can occur anytime after the pilot burner is lit. Failure code timing is 1/4 second on, 1/2 second off.

Sequence is failure code followed by LED not blinking for four seconds.

In the event of multiple failure codes, the next failure code follows the previous failure code by approximately three seconds.

Code Service Action

8 Replace valve

7 Conrm stepper motor connection exists

4 Fuel conversion plug missing or has poor connection (RV8310E only)

3 Replace thermopile with Q313

2 Device too hot. Check application

1 None required. This is normal operation and indicates the control is powered
