VFC 15-150 - VFC 45-225 MODULATING GAS BOILERS
CODE REQUIREMENTS
TheVFC15-150modelwastestedtoandcertiedunderCSA4.9-2000/ANSI
Z21.13-2000. The larger VFC 45-225 unit was approved under CSA 4.9a-2005 /
ANZI Z21.13a-2005.
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
VFC-series boilers are designed and approved for indoor installation (wall or rack
mounting),withsignicantexibilityoflocationprovidedwiththeavailableventing
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
vapourswhichcanformcorrosiveacidcompoundswhenburnedinagasame.
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: 150 lbs / 68 kg without water. Use - as a minimum - 4 x #12 size
2" lag screws or 1/4" bolts (with metal mounting systems). 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 10” 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

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.
