SAFETY RULES
The Direct Vent Gas Wall/Window Heater and its components meet all applicable safety standards when installed as
directed in this manual. For safe installation and operation of your Direct Vent Gas Wall/Window Heater, read all
these instructions before you begin. Failure to follow them exactly will void your warranty and may result in fire,
property damage, personal injury, and loss of life.
1.
2.
3.
Improper installation, adjustment, alteration, service, or maintenance can cause property damage, bodily
injury, or death.
Use in residential application only, non residential installation will void the warranty, and may result in property
damage, personal injury and loss of life.
The installation must conform with local codes or in the absence of local codes with the National Fuel Gas
Code, ANSI Z223.1/NFPA54, Natural Gas and Propane Installation Code, CSA B149.1. A copy may be
obtained from the CSAInternational, or the National Fire ProtectionAssociation, Batterymarch Park, Quincy,
MA. 02269. In Canada, use latest edition of CAN1-B149 installation code.
DO NOT INSTALL THIS FURNACE IN A RECREATIONAL VEHICLE.
Do not operate this heater unless the factory installed vent system is in place.
Check the rating label to be sure heater is equipped for the type gas you intend to use.
Never use a match, candle, flame or other source of ignition to check for gas leaks. Use only soapy water,
liquid detergent, or an approved gas leak solution.
4.
5.
6.
7.
8.
9.
Your heater, including vent system must be inspected at least annually by a qualified service technician.
Before cleaning or servicing, turn off the gas and allow heater to cool.
10.
11.
12.
Do not operate heater without all components properly installed.
Due to high temperatures, the heater should be located out of traffic and away from furniture and drapes.
Children and adults should be alerted to the hazard of high surface temperature and should be kept away
to avoid burns or clothing ignition.
13.
14.
15.
Young children should be carefully supervised when they are in the same room with the heater.
Do not place clothing or other flammable material on or near the heater.
INSTALLATION AND REPAIR MUST BE DONE BY A QUALIFIED SERVICE PERSON. THE
HEATER MUST BE INSPECTED BEFORE USE AND AT LEASTANNUALLY BYA PROFESSIONAL
SERVICE PERSON. More frequent cleaning may be required due to excessive lint from carpeting, bedding
material, etc. It is imperative that control compartments, burner, and circulating air passageways of the
heater be kept clean.

17.
Do not install in a closet, alcove, or small hallway where the heater could be isolated from the space to
be heated by closing a door.
Do not place anything around the heater or vent that will obstruct the flow of combustion and
ventilation air. Special note must be taken outside the home in regard to shrubs, flowers, trees, etc., including
snow build-up on top of these items that could block the air intake or vent exhaust tubes.
The appliance, when installed, must be electrically grounded in accordance with local codes or, in the
absence of local codes, with the latest edition of National Electrical Code, ANSI/NFPA 70. In Canada, use
CSA C22.1.
18.
19.
20.
21.
Never operate this heater without the burner sight glass in place or with the glass broken or missing.
If it is suspected that rising water may enter the heater, turn off the gas immediately.
Do not use the heater if any part has been under water. Immediately call a qualified service technician
to inspect and clean the appliance and to replace any part of the control system and any gas control which
has been under water.
22.
Damaged gaskets or sealing material within the vent or air intake system must be replaced prior to operating

be installed so that all burners and burner ignition devices are located not less than 18 inches {46 cm}
above the floor.
Unit should be located or protected so it is not subject to damage by a moving vehicle. Use care in
selecting a good location within the garage. DO NOT locate the heater where heated air will be
directed onto a nearby parked vehicle, as vehicle paint may discolor or rubber may harden and crack.
DONOTallowopenorclosedcontainersofpaint,gasolineorotherliquidshavingflammablevaporstobe

Gas supply line must be 3/8” minimum. Consult gas supplier, local code agency, orANSI Z223.1 for
propersizingandroutingofsupplyline.
Unit must have a grounded 115 v. electrical outlet. Heater is equipped with a 3-prong, 9 ft. factory
installed power cord.

STEP 3 - LOCATE THERMOSTAT
1.
2.
Thermostat must be installed in same room as heater.
Locate thermostat on an inside wall approximately 5 feet {153 cm} above the floor and at least 6 feet
{183 cm}from the heater.
3.
4.
5.
Do not locate thermostat so as to be effected by heat from sources other than the heater (i.e. direct
sunlight, lamps, T.V. sets, radiators, registers, etc.).
Do not locate thermostat in unusually cool locations (i.e. outside wall, on a wall separating the heated
area from an unheated area, in drafts from stairwells, doors, windows, etc.).
Install thermostat where there is good air circulation and where it is readily accessible for wiring, service
and adjustment. Never install in a corner, alcove, over or behind furniture or behind a door.
STEP 4 - GAS SUPPLY ROUGH-IN
1.
An inch and a half (1-1/2”) opening is provided toward the right front of the liner bottom for installation
of the gas supply line. This opening facilitates installation of a gas supply line located inside the room
where the heater is installed. If the gas supply line is located in a stud space or other concealed area
consult the gas supplier, local code officials or the latest edition of ANSI Z223.1/NFPA 54 for special
instructions and approval for a concealed gas supply line. NOTE: If gas supply line is concealed, it must
be brought into the room under the heater as there must be a manual shut-off valve installed in the
gas supply line that is accessible from inside the room where the heater is installed.
The valve must be connected only by means of a pipe union of the ground joint type.
Mr. Installer, support gas valve, with a second wrench, when connecting the gas supply line, to prevent
damage.
2.
3.
4.
5.
Install at least 3/8” gas supply line. Contact local gas supplier if any questions.
Install a drip leg in gas supply line immediately upstream from the gas connection to heater. (see local
codes), and provide a 1/8” N.P.T. plugged tapping, accessible for test gauge connection and an indi-
vidual manual shut off valve accessible within room where heater is installed. (See Figure 4). The heater
and its individual shut off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2 psig (3.5Pa). The heater must be
isolated from the gas supply piping system by closing its individual manual shut off valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5Pa).
Test all connections for leaks using a soapy solution. NEVER USE AN OPEN FLAME TO TEST
FOR LEAKS.
6.
7.
8.
The maximum inlet gas supply pressure for natural or L.P./Propane gas is 1/2 p.s.i. or 14” w.c.
The minimum inlet gas supply pressure for the purpose of adjustment is 4.5” w.c. for natural gas or
11.0” w.c. for L.P./Propane gas.

FOR YOUR SAFETY READ BEFORE OPERATING
WARNING: If you do not follow these instructions exactly, a fire or explosion may result
causing property damage, personal injury or loss of life.
A.
B.
This appliance does not have a pilot. It is
equipped with an ignition device which
automatically lights the burner. Do not try
to light the burner by hand.

control knob. Never use tools. If the knob will
not push in or turn by hand, don’t try to repair
it, call a qualified service technician. Force or
attempted repair may result in a fire or explosion.
BEFORE OPERATING smell all around the
appliance area for gas. Be sure to smell next
to the floor because some gas is heavier than
air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS:
• Do not try to light any appliance.
• Do not touch any electric switch; do not
use any phone in your building.
• Immediately call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
Do not use this appliance if any part has been
under water. Immediately call a qualified service
