Monessen Hearth DLY18 Installation And Operating Instructions Manual page 4

IMPORTANT SAFETY INFORMATION
15. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
16. Unvented gas heaters are a supplemental zone
heater. They are not intended to be a primary heat-
ing appliance. Water vapor produced by an
unvented heater can create moisture problems in a
home when operated for extended periods of time.
17. During manufacturing, fabricating and shipping,
various components of this appliance are treated
with certain oils, films or bonding agents. These
chemicals are not harmful but may produce annoy-
ing smoke and smells as they are burned off during
the initial operation of the appliance; possibly caus-
ing headaches or eye or lung irritation. This is a
normal and temporary occurrence.
The initial break-in operation should last 2-3 hours
with the burner at the highest setting. Provide maxi-
mum ventilation by opening windows or doors to
allow odors to dissipate. Any odors remaining af-
ter this initial break-in period will be slight and will
disappear with continued use.
18. 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 per-
cent for each 1,000 feet above sea level. Refer to
the National Fuel Gas Code.
19. The heater and its individual shutoff 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).
20. The heater must be isolated from the gas supply
piping system by closing its individual manual
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).
21. Do not use this room heater if any part has been
under water. Immediately call a qualified 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.
22. This appliance must not be used with glass doors
in the closed position. This can lead to pilot out-
ages and severe sooting outside the fireplace.

sions for combustion air are provided, the screen
shall have an opening(s) for induction of combus-
tion air.
This appliance may be installed in an
aftermarket, permantly located, manufactured
