Failure to keep boiler area clear and free of combustible materials, liquids, and vapors can result in substantial property damage,
severe personal injury, or death.
4. Gas control system components must be protected from dripping water
during operation and service.
5. If the boiler is to replace an existing boiler, check for and correct any
existing system problems, such as:
System leaks
Location that could cause the system and boiler to freeze and leak.
Incorrectly-sized expansion tank
6. Clean and flush system when reinstalling a boiler.
NOTE: When installing in a zero clearance location, it may not be possible
to read or view some product labeling. It is recommended to make note of
the boiler model and serial number.
Do not mount the boiler to a hollow wall. Mount to the studs only. Failure
to do so will result in substantial property damage, and could result in
severe personal injury or death.
Use extreme care not to drop the boiler or cause bodily injury while lifting
or mounting the boiler onto the optional wall mount bracket. Failure to do
so will result in property damage, and could result in severe personal
injury or death.
Gas conversion should be performed BEFORE the boiler is installed. Carefully follow the gas conversion instructions when performing
the conversion. Failure to do so could result in property damage, severe personal injury, or death.
B. LEVELING AND DIMENSIONS
C. CLEARANCES FOR SERVICE ACCESS
See Figure 2 for recommended service clearances. If these minimum
clearances are not provided, it may not be possible to service the boiler
without removing it from the space.
MINIMUM CLEARANCES FROM COMBUSTIBLE MATERIALS
Hot water pipes
– at least 1” from combustible materials.
Exhaust vent pipe
– at least 1” from combustible materials.
Space must be provided with combustion/ventilation air openings correctly sized for all other appliances located in the same space as
the boiler. The boiler cover must be securely fastened to prevent it from drawing air from the boiler room. This is particularly important if
the boiler is in a room with other appliances. Failure to comply with the above could result in substantial property damage, severe
personal injury, or death.
In order for the condensate to properly flow out of the collection
system, the area where you locate the boiler must be level. The
boiler comes equipped with leveling feet. Should you find the
floor beneath the boiler is uneven, adjust the leveling feet with a
wrench.
