lation Code, CSA C22.1 Canadian Electrical Code Part 1 and any
local codes.
e Ultra boiler gas manifold and controls met safe
lighting and other performance criteria when boiler un-
derwent tests specied in ANSI Z21.13 — latest edition.
1. Check for nearby connection to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
• Condensate drain
2. Check area around boiler. Remove any combustible materials,
gasoline and other ammable liquids.
Failure to keep boiler area clear and free of combustible
materials, gasoline and other ammable liquids and
vapors can result in severe personal injury, death or
substantial property damage.
3. e Ultra boiler must be installed so that gas control system com-
ponents are protected from dripping or spraying water or rain
during operation or service.
4. If new boiler will replace existing boiler, check for and correct
system problems, such as:
• System leaks causing oxygen corrosion or heat exchanger cracks
from hard water deposits.
• Incorrectly-sized expansion tank.
• Lack of freeze protection in boiler water causing system and
boiler to freeze and leak.
Clearances from combustible materials
1. Hot water pipes — at least ½” from combustible materials.
2. Vent pipe — at least
3/16” from combustible materials.
3. See Figure1 for other clearance minimums.
Clearances for service access
1. See Figure1 for recommended service clearances. If you
do not provide minimum clearances shown, it might
not be possible to service the boiler without removing
it from the space.
1. Ultra boilers can be wall mounted (using special wall
mount kit) or oor mounted. No clearance is re-
quired at the rear of the unit
, either for service or
for clearance to combustible surfaces.
2. Boilers can be wall mounted ONLY if using the optional
wall-mount kit available from WM Technologies. See
page50 for instructions.
