2.0 Before installation
Before installing the appliance, it is important to review and observe the following checklist of
precautions:
Precautions Check
Care must be taken to properly size the boiler for its intended use. Prolonged full fire run
time, over-sizing or under-sizing, and incorrect flow rates through the appliance can lead to
increased maintenance costs, equipment stress and premature failure.
□
Ensure you install the appliance where the combustion air source is not subject to
chemical fouling or agricultural vapors. Exposure to corrosive chemical fumes such as
chlorinated and/or fluorinated hydrocarbons can reduce the life of a boiler. Cleaners,
bleaches, air fresheners, refrigerants, aerosol propellants, dry-cleaning fluids, de-greasers
and paint-removers all contain vapors that can form corrosive acid compounds when
burned in a gas flame. Airborne chlorides such as those released with the use of laundry
detergents are also to be avoided.
□
Locate the appliance where water leakage will not result in damage to the area. If there is
no suitable location, install a suitable drain pan under the boiler. Do not install above
carpeting.
□
At a new construction site, or during renovations, protect the appliance from drywall dust or
other construction-related contaminants. Draw combustion air from a
clean source (e.g.,
outdoors) and isolate the boiler from interior dust sources. Do not seal boiler case
openings directly when firing - allow for air circulation and ventilation in the immediate
area.
□
Place the exhaust outlet 12" minimum above the down-turned intake to avoid exhaust re-
ingestion.
□
For sidewall venting options, place the inlet and exhaust terminations on the same side of
the building. The elevation of both pipes can be raised in “periscope style” after passing
through the wall to gain required clearance above grade and snow level.
□
If using the indoor combustion air option, ensure combustion air openings to the boiler
room remain unblocked and free of obstructions.
□
Examine the condensate outlet to ensure proper disposal of condensate will occur during
operation. If condensates are to be discharged into building drain piping materials that are
subject to corrosion, a neutralization package must be used.
□
Ensure that the pressure relief valve is installed with no valves or other means of isolation
between its inlet and the boiler. Make sure the relief valve outlet is piped with unobstructed
piping (minimum ¾" diameter) to a safe discharge location.
□
If the appliance is likely to be exposed to fluid temperatures below 34° F (1° C), a method
of protection to prevent freezing of condensate should be employed. Contact the factory
for further information.
□
When the appliance is in operation, assess the impact of the steam plume typical of a
condensing boiler's exhaust terminal. Generally, intake and exhaust pipes should
terminate at a rooftop or sterile wall location. Boiler condensate is corrosive. Protective
