Monessen • AVFL60 Installation Manual • 4605-901 Rev. A • 05/17

D. Getting Started

Verify that all listed parts have been received. You should

have the following:

• Unvented gas heater

• Two (2) anchoring screws

• Installation and Owner’s instructions

• 6" non-combustible board

• Deector glass

• Five (5) bags reglass

• Two (2) 90 watt bulbs

• RC300 remote control

Carefully inspect the contents for shipping damage. If any

parts are missing or damaged, immediately inform the

dealer from whom you purchased the appliance. Do not
attempt to install any part of the appliance unless you
have all parts in good condition.

F. Adequate Combustion Ventilation Air

This heater shall not be installed in a conned space or

unusually tight construction unless provisions are provided

for adequate combustion and ventilation air.
The National Fuel Gas Code, (ANSI Z223.1/NFPA54),

denes a conned space as a space whose volume is less
than 50 cubic feet per 1,000 BTU per hour (4.8m

3

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 a conned space.
Unusually tight construction is dened as construction

where:
a. Walls and ceilings exposed to the outside atmosphere

have a continuous water vapor retarder with a rating of

1 perm (6 x 10

11

kg per pa/sec-m2) or less with openings

gasketed or sealed, and

b. Weather stripping has been added to 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 plumbing, electrical and gas

lines and other openings.

The following formula can be used to determine the maxi-

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

BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft

50

Consider two connecting rooms with an open area
between, with the following dimensions:

L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.

BTU/Hr = (151/2 + 12) x (12) x (8)

50

If there were a door between the two rooms the calculation

would be based only on the room with the heater.

BTU/Hr = (151/2) x (12) x (8)

50

Do not install the heater:

• Where curtains, furniture, clothing, or

other ammable objects are less than

36" from the front of the heater.

• In high trafc areas.

• In windy or drafty areas.

E. Planning the Installation

When planning the installation of the replace it is neces­sary to determine where the unit is to be installed and

whether optional accessories are desired. Gas supply
piping should also be planned. The following steps repre­sent the normal sequence of installation. Each installation
is unique, however, and might require a different sequence.

1. Position replace in desired location. Refer to the Fire-

place Location (page 8, Figure 3.2) and Clearances
and Height Requirements (page 9, Figures 3.4 and 3.5)

Figure 3.6 Good Faith TV Guidelines

C. Good Faith Wall Surface TV Guidelines

Good Faith Guidelines for TV Installaons above a Typical Gas Fireplace

Notes:

1. TV installation as shown requires the mantel be constructed entirely of noncombustible material
as it is below the allowable height for a combustible mantel.

2. These are good faith recommended clearances only and not a guarantee of compliance with all TV
manufacturers’ maximum allowable operating temperatures.

3. Since every home has unique air ow characteristics and maximum allowable operating temperatures
can vary from manufacturer to manufacturer and from model to model, actual TV temperatures should be
validated at the time of each installation. TVs should not be used in situations where the actual TV
temperature exceeds the manufacturers’ maximum allowable operating temperatures identied in the
TV’s technical specications. Contact the TV’s manufacturer directly if you cannot locate this information
or have questions regarding the information.

E. Floor Protection

NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.

WARNING! Risk of Fire! Maintain specied air space

clearances to appliance and vent pipe:

• Insulation and other materials must be secured to prevent

accidental contact.

• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and

making contact with replace or chimney.

• Failure to maintain airspace could cause overheating
and re.

Figure 3.7 Floor Protection

D. Constructing the Appliance Chase

A chase is a vertical box-like structure built to enclose the

gas appliance.

NOTICE: Construction of the chase may vary with the type
of building. These instructions are not substitutes for the
requirements of local building codes. Therefore, you MUST
check local building codes to determine the requirements
to these steps.

Chases should be constructed in the manner of all out­side walls of the home to prevent cold air drafting prob-

lems. The chase should not break the outside building
envelope in any manner.

Walls, ceiling, base plate and cantilever oor of the chase
should be insulated. Vapor and air inltration barriers

should be installed in the chase as per regional codes for

the rest of the home. Additionally, in regions where cold
air inltration may be an issue, the inside surfaces may be

sheet rocked and taped (or an equivalent method may be

used) to achieve maximum air tightness.

To further prevent drafts, the wall shield and ceiling re-

stops should be caulked with caulk with a minimum of

300ºF continuous exposure rating to seal gaps. Gas line

holes and other openings should be caulked with caulk

with a minimum of 300ºF continuous exposure rating or
stuffed with unfaced insulation. If the appliance is being

installed on a cement surface, a layer of plywood may be
placed underneath to prevent conducting cold up into the

room.

Note: Figure 3.4 and Figure 3.5, and Figure 3.7 show the
replace installed on the oor. However, this replace can
be elevated off the oor provided that the replace is properly

supported by framing materials and the ceiling clearances are

maintained.

Appliance Preparation

A. Securing and Leveling the Appliance

WARNING! Risk of Fire! Prevent contact with:

• Sagging or loose insulation

• Insulation backing or plastic

• Framing and other combustible materials

Block openings into the chase to prevent entry of blown­in insulation. Make sure insulation and other materials
are secured.

DO NOT notch the framing around the appliance
standoffs. Failure to maintain air space clearance could

cause overheating and re.

To properly position, level, and secure the appliance, see

below. Nailing tabs are provided to secure the appliance
to the framing members.

• Bend out the two nailing tabs on each side.

• Place the appliance into position.

• Keep nailing tabs ush with the framing. See Figure 4.2.

• Level the appliance from side to side and front to back.

• Shim the appliance as necessary. It is acceptable to use
wood shims underneath the appliance.

• Secure the appliance to the framing by using nails or

screws through the nailing tabs.

Some gures in manual show the replace installed on the
oor. However, this replace can be elevated off the oor
provided that the replace is properly supported by framing
materials and the ceiling clearances are maintained.

D. Connect to Gas

NOTICE: A qualied gas appliance installer must connect

the heater to the gas supply. Consult all local codes.

Use new black iron or steel pipe. Internally
tinned copper or copper tubing can be used
per National Fuel Code, section 2.6.3, providing

gas meets hydrogen sulde limits, and where

permitted by local codes. Gas piping system
must be sized to provide minimum inlet
pressure (Listed on Data Plate) at the maximum

ow rate (BTU/hr). Undue pressure loss will

occur if the pipe is too small.
A manual shutoff valve must be installed
upstream of the appliance. Union tee and
plugged 1⁄8" NPT pressure tapping point should
be installed upstream of the appliance. Figure

5.3
A sediment trap should be installed upstream
to prevent moisture and contaminants from
passing through the pipe to appliance controls
and burners. Failure to do so could prevent the
appliance from operating reliable. Figure 5.3

IMPORTANT: Loosen the pipe adapter on the ex tube

before installing to the system piping.

ers only, to reduce the supply tank pressure to a maximum

of 13" w.c. This is in addition to the internal regulator in the
heater valve.

When tightening the joint to the valve, hold the valve

securely to prevent movement.

Test all gas joints from the gas meter to the heater valve for

leaks using a gas analyzer or soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.

CHECK GAS TYPE: The gas supply must be the
same as stated on the heater’s rating plate. If
the gas supply is different, DO NOT INSTALL
THE HEATER. Contact your dealer for the

Gypsum wallboard (drywall) joints can be nished up to

the perimeter of the left, right and bottom edge of the unit

ush with the face. The 6” of suppied nom-combustible

must be used at the top of the unit where the gypsum

board can then be nished to the left, right and top edge
of the non-combustible board.

• Finishing Around Opening of Unit (Install Option #2)

NOTE: With this installation option, the unit must be

recessed to the depth of the non-combustible being used

to ensure nish is ush with surrounding wall. This is

the recommended install option for all trim kits such as

the AVFL60TKI, AVFL60CFCV, AVFL60CFBT. Refer
to Trim Kit instructions for Option #2 installation before
starting.

The 6” non-combustible must rst be installed above

the unit in the same manor as insatllation option #1,

ush with the top face of the unit. In this option, non-

combustible is required for all material covering the face

of the unit. The non-combustible may be installed up to
the rebox opening but must not overlap which would
impede the removal of the screen. When installing
material around the rebox opening, install the sheet
with a pre-cut hole for the rebox opening in a single
sheet, if possible. This will minimize joints across the
replace face and reduce cracking.

To Reduce the Risk of Sheetrock Cracking:

DO

Use all purpose joint compound.

Use eggshell paint
(100% acrylic latex paint, gloss or semi-gloss).

To Avoid Sheetrock Cracking:

DO NOT

Use a quick set or light weight joint compound.

Use at paint.

In extreme cases, lab tests have shown yellow pigments

fading out of paints over time due to heat. Vent run and

installation location will have an effect on wall temperature

and fading. If fading occurs, consider avoiding paint that
contains yellow pigment.

In regards to the sheetrock mud, apply a smooth, even

layer, covering a wide area of the wall for the best results.
For best results, follow the tips below.

WARNING! Risk of Fire! DO NOT apply combustible
materials beyond the minimum clearances. Comply with

all minimum clearances to combustibles as specied in

this manual. Overlapping materials could ignite and will
interfere with proper operation of doors and louvers.

WARNING! Risk of Fire! DO NOT install drywall or
other combustible materials directly onto the installed
non-combustible board. Overlapping materials could
ignite.

Finish with non-combustible
up to unit opening. Cannot
cover the opening so that
screen can be removed.

Figure 8.3 Control Module

Control Module Operation

1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 8.3.

OFF Position: Appliance will ignore all power inputs and

will not respond to any commands from a wall switch or

remote. The unit should be in the OFF position during

installation, service, battery installation, fuel conversion,

and in the event that the control goes into LOCK-OUT
mode as a result of an error code.

ON Position: Appliance will ignite and run continuously

in the HI ame setting, with no adjustment in ame
output. This mode of operation is primarily used for

initial installation or power outage operation with battery

backup.

REMOTE Position: Appliance will initiate commands

from an optional wired wall switch and/or the wireless

remote (RC300).

2. If using a wired wall switch with the module in REMOTE
mode, the ame output can be adjusted with the HI/LO
selector switch on the module. See Figure 8.3. Note
that the ame HI/LO selector switch will become inactive
once an optional remote control (RC200/RC300) is
programmed to the control module. Note that the control
module will always ignite the replace on HI and remain
so for the initial 10 seconds of operation. If the HI/LO
is switched to the LO position, the ame output will
automatically drop to the lowest setting after the ame
has been established for 10 sec. After this 10 second
period, the ame can be adjusted from HI to LO with
the switch.

3. The control module has safety feature that automatically
shuts down the replace after 9 hours of continuous
operation without receiving a command from the RC300
remote.

4. If you intend to use both an optional wired wall switch
and the RC300 remote control to operate your replace,

the wall switch will override any commands given by

the remote.

5. Module Reset

This module may lock-out under certain conditions.

When this occurs, the appliance will not ignite or

respond to commands. The module will go into

lock-out mode by emitting three audible beeps, then

continuously displaying a RED/GREEN error code at
its status indicator LED.

• Check battery tray. Remove batteries if installed.

Batteries should only be installed for use during power

outages.

• Locate the module selector switch. (See Figure 8.3).

• Set the module selector switch to the OFF position.

• Wait ve (5) minutes to allow possible accumulated gas
to clear.

• Set the module selector switch to ON or REMOTE
position.

• Start the appliance.

WARNING! Risk of Explosion! DO NOT press the mod-

ule reset switch more than one time within a ve min­ute time period. Gas could accumulate in rebox. Call a
qualied service technician.
