17. Unvented gas heaters are a supplemental zone heater.
They are not intended to be the primary heating
appliance.
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, fi 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 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 qualifi 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 fi replace where a unvented
room heater is installed.
25. Always have a fireplace screen in place when the
appliance is in operation and, unless other provisions
for combustion air are provided, the screen must have
an opening(s) for induction of combustion air.
