Code Requirements; Location - IBC DC Series Installation And Operating Instructions Manual

WARNING
Keep boiler / water heater 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 / water heater
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.)

CODE REQUIREMENTS

The DC 15-95, DC 15-96, DC 20-125, DC 33-160 models were tested to and
certified under CSA 4.9 / ANSI Z21.13 and Water Heater CSA 4.3 / ANSI
Z21.10.3.
The installation must conform to the requirements of the authority having
jurisdiction or, in the absence of such requirements, to the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, and/or Natural Gas and Propane Installation Code,
CAN/CSA B149.1. The installation must also conform to the Canadian Electrical
Code Part 1 CSA C22.2 No.1 and/or 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 will apply.

LOCATION

The DC series boilers / water heaters are designed and approved for indoor
installation (wall), with significant flexibility of location provided with the available
venting options. The boiler / water heater 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 / water heater 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 / water heater. 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. Similarly, ensure any direct vent air
source is not adjacent to a clothes dryer exhaust terminal. Avoid agricultural
applications where the boiler / water heater and/or the intake air source are
affected by ammonia and/or dust.
Locate the boiler / water heater 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 / water heater is not to be installed
above carpeting.
Boiler / Water Heater Weight – approximately 105 lb / 44 kg. For support fasteners,
use the supplied 4 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 / water heater and piping
assembly components.
Other factors affecting potential mounting sites:
•
Ensure minimum clearance requirements for combustible materials (see
Table 2) are satisfied.
•
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 / water heater from drywall dust or other construction
related contaminants; combustion air should be drawn from a CLEAN
source (e.g. outdoors) and the boiler / water heater should be isolated
from interior dust sources.
