Code Requirements; Location - IBC SL 14-115 G3 Installation And Operating Instructions Manual

WARNING
Keep boiler area free and clear of
combustible materials, gasoline,
and other flammable vapours and
liquids.
WARNING
Combustion air must not be
drawn from areas containing
corrosive air from swimming
pools or spas, including air
directly next to outdoor pools
and spas.
WARNING
The boiler shall not be exposed
to water leaks from piping or
components located overhead.
This includes condensation
dropping from un-insulated cold
water lines overhead.
WARNING
Ensure the gas ignition system
components are protected from
water (dripping, spraying, rain,
etc.) during appliance operation
and when servicing (pump
replacement, condensate trap
servicing, control replacement,
etc.)
INSTALLATION
SL 14-115 G3, SL 20-160 G3, SL 30-199 G3 MODULATING GAS BOILERS SL 14-115 G3, SL 20-160 G3, SL 30-199 G3 MODULATING GAS BOILERS

1.2 CODE REQUIREMENTS

The SL models were tested to and certified under CSA 4.9-2014 / ANSI Z21.13-2014.
Installation must conform to local codes, or in the absence of these, with the latest editions
of CAN/CGA B149.1 and the Canadian Electrical Code Part 1 CSA C22.2 No. 1.
In the US, installations must conform to the current National Fuel Gas Code ANSI
Z223.1 and the National Electrical Code ANSI/NFPA 70. Where required by jurisdiction,
installation must conform to the Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-1. If there is any conflict, then the more
stringent requirement will apply.

1.3 LOCATION

The SL series boilers are designed and approved for indoor installation (wall or rack
mounting), with significant flexibility of location provided with the available venting options.
The boiler can be placed in an alcove, basement, closet or utility room. Surrounding
conditions shall be 0°C to 50°C and less than 90% relative humidity.
Install the boiler in areas 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 which 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. For this reason, the indoor air venting option using air surrounding
the boiler should not be used in a laundry room. Similarly, ensure any direct vent air
source is not adjacent to a clothes dryer exhaust terminal. Avoid agricultural applications
where the boiler and/or the intake air source are affected by ammonia and/or dust.
Locate the boiler where water leakage will not result in damage to the area. If a location
such as this cannot be found, a suitable drain pan should be installed under the appliance.
The boiler is not to be installed above carpeting.
Boiler Weight – up to 150 lbs / 68 kg. For support fasteners, use the supplied 6 x 1/4" x
2 1/2" long lag screws. Installer to supply 1/4" bolts if metal mounting systems are used.
Fasteners are to be attached to solid material capable of supporting the combined weight
of the boiler and piping assembly components.
Other factors to consider for potential mounting sites:
• The minimum clearance requirements for combustible materials (see
Table 2).
• A minimum 24" clearance at the front and 10" above the boiler is recommended for
adequate servicing. Check local codes for additional access and service clearance
requirements.
• At a new construction site, or during renovations, action must be taken to protect
the boiler from drywall dust or other construction related contaminants; combustion
air should be drawn from a CLEAN source (e.g. outdoors) and the boiler should be
isolated from interior dust sources.
