3. Ensure that the floor is structurally sound and will
support the weight of the boiler/water heater.
NOTE: Never install a Series 8800 or 8900 boiler/
water heater on a concrete floor that contains wires,
cables, water pipes or hoses. This boiler/water
heater is designed for noncombustible floors only!
Never install this boiler/water heater on combustible
materials or carpeting even if a non-combustible
foundation material is placed over them!
4. Locate the boiler/water heater in an area that will
prevent water damage to adjacent construction
should a leak occur or during routine maintenance.
If such a location doesn't exist, a suitable drain pan
that's adequately drained must be installed under
the unit. The pan must not restrict the flow of
combustion air to the unit.
5. DO NOT place this boiler/water heater in a location
that would restrict the introduction of combustion air
into the unit or subject it to a negative pressure, see
"GENERAL VENTING GUIDELINES".
6. NEVER place this boiler/water heater in a location
that would subject it to temperatures at or near
freezing.
WARNING: Never store combustible materials,
gasoline or any product containing flammable vapors
or liquids in the vicinity of the boiler/water heater.
Failure to comply with this warning can result in an
explosion or fire causing extensive property damage,
severe personal injury or death!
COMBUSTION AIR & VENTILATION
WARNING: This boiler/water heater must be
supplied with combustion air in accordance with
Section 5.3, Air for Combustion & Ventilation, of
the latest revision of the National Fuel Gas
Code, ANSI Z223.1/ NFPA 54 and all applicable
local building codes. Canadian installations
must comply with CAN/ CGA B149.1 or .2
Installation Code for Gas Burning Appliances
and Equipment, or applicable provisions of the
local building codes. Failure to provide adequate
combustion air for this boiler/water heater can
result in excessive levels of carbon monoxide
which can result in severe personal injury or
death!
SERIES 8800 & 8900 INSTALLATION AND OPERATING INSTRUCTIONS
To operate properly and safely this boiler/water heater
requires a continuous supply of air for combustion.
NEVER store objects on or around the boiler/water heater!
CAUTION: Combustion air contaminated with
fluorocarbons or other halogenated compounds
such as cleaning solvents and refrigerants will
result in the formation of acids in the combustion
chamber. These acids will cause premature failure
of the boiler/water heater voiding the warranty!
CAUTION: If the boiler/water heater is operated
while the building is under construction it MUST be
protected from wood, concrete, sheet rock and
other types of dust. Failure to properly protect the
unit from construction dust will damage the unit
voiding the warranty!
All Air From Inside The Building
If the boiler/water heater is to be located in a confined
space minimum clearances listed in Table 1 or 1A must
be maintained between the boiler/water heater and any
combustible construction. When installed in a confined
space, Figures 1, 2, 3, 4 and 5, two permanent openings
communicating with an additional room(s) are required.
The combined volume of these spaces must have
sufficient volume to meet the criteria for an unconfined
space. The total air requirements of all gas utilization
equipment, fireplaces, wood stoves or any type of
exhaust fan must be considered when making this
determination. Each opening must have a minimum free
/1000 Btu/hr, 2200 mm
area of 1 in
2
total input rating of ALL gas utilization equipment in the
confined area. Each opening must be no less than
, 64,516 mm
100 in 2 in size. The upper opening must
2
be within 12 in, 305 mm of, but not less than 3 in,
76 mm from, the top of the enclosure. The bottom
opening must be within 12 in, 305 mm of, but not less
than 3 in, 76 mm from, the bottom of the enclosure.
All Air From Outside The Building
When installed in a confined space two permanent
openings communicating directly with, or by ducts
to, the outdoors or spaces that freely communicate with
the outdoors must be present. The upper opening must
be within 12 in, 305 mm of, but not less than 3 in,
76 mm from, the top of the enclosure. The bottom
opening must be within 12 in, 305 mm of, but not less
than 3 in, 76 mm from, the bottom of the enclosure.
Where directly communicating with the outdoors
or communicating with the outdoors through vertical
ducts, each opening shall have a minimum free area
/4000 Btu/hr, 550 mm
of 1 in
2
rating of all of the equipment in the enclosure.
