IMPORTANT SAFETY INFORMATION
Continued from page 3
16. Keep room area clear and free from combustible materi-
als,gasolineandotherammablevaporsandliquids.
17. Unvented gas heaters are a supplemental zone heater.
They are not intended to be a primary heating appli-
ance.
18. Unvented gas heaters emit moisture into the living area.
In most homes of average construction, this does not pose
a problem. In houses of extremely tight construction,
additional mechanical ventilation is recommended.
19. During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils,lmsorbondingagents.Thesechemicalsarenot
harmful but may produce annoying smoke and smells
as they are burned off during the initial operation of the
appliance; possibly causing headaches, or eye or lung
irritation. This is a normal and temporary occurrence.
The initial break-in operation should last two to three
hours with the burner at the highest setting. Provide
maximum ventilation by opening windows or doors to
allow odors to dissipate. Any odors remaining after this
initial break-in period will be slight and will disappear
with continued use.
20. Input ratings are shown in BTU per hour and are for
elevations up to 2,000 feet. For elevations above 2,000
feet, input ratings should be reduced 4 percent for each
1,000 feet above sea level. Refer to the National Fuel
Gas Code.
21. The appliance and its appliance main gas 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 (3.5 kPa).
22. The appliance must be isolated from the gas supply
piping system by closing its equipment shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig
(3.5 kPa).
23. Do not use this room heater if any part has been under
water. Immediatelycallaqualiedservicetechnician
to inspect the room heater and to replace any part of the
control system and any gas control which has been under
water.
24. Neverburnsolidfuelsinareplacewhereaunvented
room heater is installed.
25. Alwayshaveareplacescreeninplacewhentheappli-
ance is in operation, and unless other provisions for
combustion air are provided, the screen shall have an
opening(s) for induction of combustion air.
26. Donotllspacesaroundthereboxwithinsulationor
other materials. These spaces must be maintained to
preventthereboxfromcomingincontactwithcom-
bustible materials.

GAS LINE INSTALLATION
Consult all local codes. All gas piping must be installed to comply with local codes, or in the absence of local codes, with
the latest edition of the National Fuel Gas Code ANSI Z223.1/NFPA54.
Remove the baseplate for ease of gas line installation. Remove three (3) screws along the front edge of the baseplate. Remove
four (4) screws which secure the baseplate to the combustion casing (two at rear and one along each side). Replace baseplate
prior to connecting gas line to heater. Consult heater installation and operating instructions for correct installation of the
heaterintotherebox.
The 1/2"gaslinemayentereitherfromtheleftsideorrightsideoftherebox.Gasaccessholesareprovidedonbothsides
oftherebox.
A listed manual shutoff valve must be installed upstream of the appliance. A union tee and plugged 1/8" NPT pressure tapping
point should be installed upstream of hte appliance.
IMPORTANT: Install main gas valve (equipment shutoff valve) in an accessible location. The main gas valve is for turning
on or shutting off the gas to the replace.
A sediment trap may be upstream of the heater to prevent moisture and contaminants from passing through trap to the heater
controls and burners. Failure to do so could prevent the heater from operating reliably. Consult applicable codes.
Anexternalregulatormustbeusedonallpropane/L.P.G.heaters,inadditiontotheregulatorttedtotheheater,toreduce
the supply tank pressure to 13" w.c. (maximum). Any copper tubing used to supply propane / L.P.G. from the tank must be
internally tinned.
Note: When connecting propane / L.P.G. vent-free room heaters, you must use pipe sealant resistant to
propane / L.P.G.
Important: Hold heater regulator with a wrench to prevent movement when connecting to inlet piping.

COMBUSTION AIR
1. Locate combustion air assembly at an exterior location which is not likely to be accidentally blocked in any manner.
Locate assemblya min. of 12" above the snow line to prevent blockage by snow accumulation.
2. Never mount the combustion air inlet assembly in a garage or storage area where combustible fumes such as gasoline
mightbedrawnintothereplace.
3. Combustion air can be drawn from the crawl space under a house when an adequate supply of air is provided by open
ventilation.
4. CAUTION: Do not take combustion air from attic space or garage space.
5. Locate air supply inlet at least 3' away from any applaince vent terminal.
6. Avoidextremelylongrunsandnumerousturnsintheductleadingfromthereplacetothecombustionairassembly.
Theseconditionsincreasetheresistancetothefreeowofairthroughtheduct.See Figures 17 through 20 for methods
of installing the outside air for combustion assemblies.
