Z21.13-2010.
Installation must conform to local codes, or in the absence of these, with the
latest editions of CAN/CGA B149 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

LOCATION
The SL series boilers are designed and approved for indoor installation (wall or
rackmounting),withsignicantexibilityoflocationprovidedwiththeavailable
venting options. The boiler can be placed in an alcove, basement, closet or utility
room. Surrounding ambient 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 vapours. Exposure to corrosive chemical
fumes such as chlorinated and/or uorinated hydrocarbons can reduce
the life of a boiler. Cleaners, bleaches, air fresheners, refrigerants, aerosol
propellants,dry-cleaninguids,de-greasersandpaint-removersallcontain

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 – without water and any effect of system piping and components
– is approx. 240 lbs/110 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 affecting potential mounting sites:
• Ensure minimum clearance requirements for combustible materials (see
Table 2)aresatised.
• Minimum 24" clearance at the front and 12” above 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
1.2
WARNING
Keep boiler area free
and clear of combustible
materials, gasoline, and
other ammable 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.
