AIR FOR COMBUSTION

AND VENTILATION

WARNING: 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. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy efcient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efcient, your home needs to breathe. Fresh air must enter your home. All fuel-burning ap-

pliances need fresh air for proper combustion

and ventilation. Exhaust fans, replaces, clothes dryers and

fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will in-

sure proper venting of vented fuel-burning

appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section

5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 4 through 6 will help you classify your space and provide adequate ventilation.

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 continuous water vapor retarder with a rating of one perm (6x10

-11

kg per pa-sec-m2) or less with

openings gasketed or sealed and

b. weather stripping 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 plumbing, electrical and gas lines and at other openings.

If your home meets all of the three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three criteria above, proceed to Determining Fresh- Air Flow For Heater Location, page 6.

Conned and Unconned Space

The National Fuel Gas Code, ANSI Z223.1/ NFPA 54 denes a conned space as a space

whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the ag-

gregate 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.

* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

_______ Btu/Hr (maximum can support) _______ Btu/Hr (actual amount used) Example:

51,200 Btu/Hr (maximum can support) 60,000 Btu/Hr (actual amount used) The space in the above example is a conned

space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support. You must provide additional fresh air. Your options are as follows:

A. Rework worksheet, adding the space of an

adjoining room. If the extra space provides an unconned space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 7.

C. Install a lower Btu/Hr heater, if lower Btu/Hr

size makes room unconned.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconned space. You will need no additional fresh air ventilation.

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 Section 5.3

or applicable local codes.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Conned or Unconned Space

Use this work sheet to determine if you have a conned or unconned space.

Space: Includes the room in which you will install

heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height =__________cu. ft.

(volume of space)

Example: Space size 20 ft. (length) x 16 ft.

(width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)

If additional ventilation to adjoining room

is supplied with grills or openings, add the

volume of these rooms to the total volume

of the space.

2. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.

______ (volume of space) x 20 = (Maximum

Btu/Hr the space can support) Example: 2560 cu. ft. (volume of space) x 20 =

51,200 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free heater ____________ Btu/Hr Gas water heater* ____________ Btu/Hr

Gas furnace ____________ Btu/Hr Vented gas heater ____________ Btu/Hr Gas replace logs ____________ Btu/Hr

Other gas appliances*

+ ___________ Btu/Hr

Total = ___________ Btu/Hr * Do not include direct-vent gas appliances.

Direct-vent draws combustion air from the outdoors and vents to the outdoors.

Example: Gas water heater ____________ Btu/Hr Vent-free heater + ___________ Btu/Hr Total = ___________ Btu/Hr

10.5" of water. If gas line pressure is higher, heater regulator damage could occur.

CAUTION: For propane/LP gas, never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

For propane/LP gas, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" and 14" of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install the external regulator with the vent pointing down as shown in Figure 16. Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new,

black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equip-

ment shutoff valve is for turning on or shutting

off the gas to the appliance. Apply pipe joint sealant lightly to male NPT

threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

* A CSA design-certied equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certied equipment shutoff valve from your dealer. See Acces- sories, page 27.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping

and connections, internal and external to unit, for leaks after

installing or servicing. Correct all leaks at once.

WARNING: Never use an

open ame to check for a leak. Apply a noncorrosive leak detection uid to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION: For propane/LP gas, make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connect- ing to Gas Supply, page 12.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1. Disconnect appliance with its appliance main gas valve (control valve) and equip-

ment shutoff valve from gas supply piping

system. Pressures in excess of 1/2 psig will damage heater regulator.

2. Cap off open end of gas pipe where equipment shutoff valve was connected.

Refer to connector's instructions

WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

Install sediment trap in supply line as shown in Figure 17. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

IMPORTANT: Hold the pressure regulator

with wrench when connecting it to gas piping and/or ttings. Do not over tighten pipe connection to regulator. The regulator body could be damaged.

remote control to control system operation. The remote receiver has a 2 position slide switch for selecting the mode of operation: REMOTE/OFF

• With slide switch in REMOTE position, system will only operate if remote receiver receives commands from remote control.

• With slide switch in OFF position, system is off.

• It is suggested that slide switch be placed in OFF position if you will be away from your home for an extended period of time. Placing slide switch in OFF position also functions as a safety lock out by both turn-

ing system off rendering remote receiver

inoperative.

General Information

Operation

• This remote control will operate gas valves latching solenoid to open gas ow to full ON.

• When ON button is pressed the remote

control sends a RF signal to the receiver. The receiver then sends a pulse of 6 volts of power to the solenoid. The solenoid then opens gas ow to burner then to full ON.

• When OFF button is pressed the remote

control sends a RF signal to the receiver. The receiver then sends a pulse of 6 volts of power to the solenoid. The solenoid then closes gas ow to burner then to full OFF.

• Heater will only work with hand held remote control. Receiver slide switch is only for positive OFF or REMOTE operation.

• The remote control will only operate heater when pilot is lit and control knob is in the ON position.

Note: Extensive use of latching solenoid

(ON/OFF) will reduce receiver’s battery life signicantly.

Code Setting

IMPORTANT: All units are shipped from fac-

tory with code switch preset to same codes. These switches must be reset to different

codes during installation to prevent interfer-

ence from another remote.

Each transmitter can use one of 255 security codes that can be reset. It WILL be necessary to set remote control and receiver code

switches to a matching security code upon initial use. If a replacement remote control

or receiver is purchased from your dealer or

factory, code switches must be set to match receiver and remote control code switches.

CLEANING AND

MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

CAUTION: You must keep control areas, burner and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualied service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

ODS/PILOT AND BURNER

Use a vacuum cleaner, pressurized air or small, soft bristled brush to clean.

BURNER PILOT AIR INLET

The primary air inlet holes allow the proper amount of air to mix with the gas. This pro-

vides a clean burning ame. Keep these holes clear of dust, dirt and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that

you clean the unit every three months during operation and have heater inspected yearly

by a qualied service person. We also recommend that you keep the burner

tube and pilot assembly clean and free of dust

and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store or

home center may carry compressed air in a

can. If using compressed air in a can, please follow the directions on the can. If you don’t follow directions on the can, you could damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

2. Inspect burner, pilot for dust and dirt.

3. Blow air through the ports/slots and holes in the burner.

4. Never insert objects into the pilot tube.

Clean the pilot assembly also. A yellow tip on the pilot ame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet about two inches from where the pilot ame comes out of the pilot assembly (see Figure

33). With the unit off, lightly blow air through

the air inlet. You may blow through a drinking straw if compressed air is not available.
