WARNING
If you do not follow these instructions exactly,
a re or explosion may result causing property
damage or personal injury.
NOTICE
Due to the low water content of the boiler, mis-
sizing of the boiler with regard to the heating
system load will result in excessive boiler cycling
and accelerated component failure. Burnham
Commercial DOES NOT warrant failures caused
by mis-sized boiler applications. DO NOT
oversize the boiler to the system. Multiple boiler
installations greatly reduce the likelihood of
boiler oversizing.
A. Installation must conform to the requirements of the
authority having jurisdiction. In the absence of such
requirements, installation must conform to the National
Fuel Gas Code, NFPA 54/ANSI Z223.1, and/or CAN/
CSA B149.1 Installation Codes.
B. Boiler is certied for installation on combustible
ooring. Do not install boiler on carpeting.
C. Provide clearance between boiler jacket and
combustible material in accordance with local re
ordinance. Refer to Figure 2 for minimum listed
clearances from combustible material. Recommended
service clearance is 24 inches from left side, front, top
and rear of the boiler. Recommended front clearance
may be reduced to the combustible material clearance
providing:
1. Access to boiler front is provided through a door or
removable front access panel.
2. Access is provided to the condensate trap located
underneath the heat exchanger.
D. Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
E. Provide combustion and ventilation air in accordance
with applicable provisions of local building codes,
or: USA - National Fuel Gas Code, NFPA 54/ANSI
Z223.1, Air for Combustion and Ventilation;
Canada - Natural Gas and Propane Installation Code,
CAN/CSA-B149.1, Venting Systems and Air Supply for
Appliances.
III. Pre-Installation and Boiler Mounting
WARNING
Adequate combustion and ventilation air must
be provided to assure proper combustion.
F. The boiler should be located so as to minimize the
length of the vent system. The PVC combustion
air piping, or the optional concentric vent piping,
containing integral combustion air inlet piping, must
terminate where outdoor air is available for combustion
and away from areas that may contaminate combustion
air. In particular, avoid areas near chemical products
containing chlorines, chlorouorocarbons, paint
removers, cleaning solvents and detergents. Avoid
areas containing saw dust, loose insulation bers, dry
wall dust etc.
CAUTION
Avoid operating this boiler in an environment
where sawdust, loose insulation bers, dry wall
dust, etc. are present. If boiler is operated under
these conditions, the burner interior and ports
must be cleaned and inspected daily to insure
proper operation.
G. General.
1. Apex boilers are intended for installations in an
area with a oor drain, or, in a suitable drain pan to
prevent any leaks or relief valve discharge to cause
property damage
2. Apex boilers are not intended to support external
piping and venting. All external piping and venting
must be supported independently of the boiler.
3. Apex boilers must be installed level to prevent
condensate from backing up inside the boiler.
4. Boiler Installation:
a. For basement installation provide a solid level
base such as concrete, where oor is not level,
or, water may be encountered on the oor
around boiler. Floor must be able to support
weight of boiler, water and all additional system
components.
b. Boiler must be level to prevent condensate from
backing up inside the boiler.
c. Provide adequate space for condensate piping or
a condensate pump if required.
