IBC Technologies Inc. 4 VFC 15-150 and VFC 45-225
1.2 CODE REQUIREMENTS
The VFC 15-150 model was tested to
and certified under CSA 4.9-2000 /
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 conflict, then the more
stringent requirement will apply.
1.3 Location
Keep boiler area free and clear of
combustible materials, gasoline, and
other flammable vapours and liquids.
VFC-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 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 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 vapours 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.
Other factors affecting potential
mounting sites:
• ensure minimum clearance
requirements for combustible
materials(see Table 2) are satisfied
• 24” clearance at the front is
recommended for adequate servicing
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.
• at a new construction site, action must
be taken to protect the boiler from
drywall dust; combustion air should
be drawn from a CLEAN source (e.g.
outdoors) and the boiler should be
isolated from interior dust sources.
Do not seal boiler case openings
directly when firing - allow for air
circulation and ventilation in the
immediate area.
