C. IMPROPER COMBUSTION
Do not obstruct the flow of combustion and ventilating air. Adequate air must be provided for safe
operation.
Attic and/or exhaust fans operating on the premises with a water heater can result in carbon monoxide
poisoning and death. Operating these fans can produce a down draft in the area of the water heater,
preventing exhaust from escaping through the chimney or vent pipe.
The venting of the water heater should be inspected by a qualified service technician at the time of
installation, and periodically thereafter, to ensure a down-draft condition does not exist.
D. EXTENDED NON-USE PERIODS
Hydrogen gas can be produced in a hot water system served that has not been used for a long period of
time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE.
To reduce risk of injury under these conditions, it is recommended to open a hot water faucet at a
convenient sink for several minutes before using any electrical appliance connected to the hot water
system.
THERE MUST BE NO SMOKING OR FLAME NEAR THE OPEN FAUCET.
If hydrogen is
present, there will probably be an unusual sound, such as air escaping through the pipe as water begins
to flow.
E. INSULATION BLANKETS
Insulation blankets available for external use on gas water heaters are not approved for use on your HTP
Oil-Fired Water Heater. The purpose of an insulation blanket is to reduce standby heat loss encountered
with storage tank water heaters. Your water heater meets or exceeds the ASHRAE/IES 90.1b standby
heat loss standards, making an insulation blanket unnecessary.
Application of an insulation blanket will
VOID THE WARRANTY
for this water heater. Furthermore, an
insulation blanket may interfere with the operation of this water heater, possibly resulting in property
damage, injury, or death.
