I. Pre-Installation
C. Appliance is design certified for installation on
combustible flooring. The boiler must not be installed
on carpeting.
D. Provide clearance between boiler jacket and
combustible material in accordance with local fire
ordinance. See Figure 2 for minimum clearance from
combustible material for closet installation. For alcove
installation provide top clearance of 27 inches and
right side clearance of 6 inches. Recommended service
clearance is 24 inches from left side, right side and
front. Service clearances may be reduced to minimum
clearances to combustible materials.
E. Install on level floor. For basement installation
provide solid base, such as concrete, if floor is not
level or if water may be encountered on floor around
boiler.
F. Install near outside wall for through wall venting.
Refer to Section V: Venting. Certified for minimum
vent length of 2 feet with one (1) elbow and maximum
vent length of 15 feet with one (1) or two (2) elbows.
WARNING
Certified as Category III appliance. Install vent
system in accordance with Section V: Venting.
Do not vent using masonry chimney, Type B gas
vent, or other Category I venting system.
G. Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
H. Provide combustion and ventilation air in
accordance with applicable provisions of local building
codes, or National Fuel Gas Code, NFPA 54/ANSI
Z223.1, Section 5.3, Air for Combustion and
Ventilation, or Sections 7.2, 7.3 or 7.4 of CAN/CGA
B149 Installation Codes.
WARNING
Adequate combustion and ventilation air must
be provided to assure proper combustion.
The following guideline is based on the National Fuel
Gas Code, NFPA 54/ANSI Z223.1.
1. Determine volume of space (boiler room). Rooms
communicating directly with space (through
openings not furnished with doors) are considered
part of space.
Volume [ft³] = Length [ft] x Width [ft] x Height [ft]
WARNING
Carefully read all instructions before installing
boiler. Failure to follow all instructions in proper
order can cause personal injury or death.
A . Inspect shipment carefully for any signs of damage.
All equipment is carefully manufactured, inspected and
packed. Our responsibility ceases upon delivery of
boiler to carrier in good condition. Any claim for
damage or shortage in shipment must be filed
immediately against carrier by consignee. No claims
for variances or shortages will be allowed by Boiler
Manufacturer, unless presented within sixty (60) days
after receipt of equipment.
B. Installation must conform to the requirements of the
authority having jurisdiction. In the absence of such
requirements, installation must conform to National
Fuel Gas Code, NFPA 54/ANSI Z223.1, and/or CAN/
CGA B149 Installation Codes. Where required by the
authority having jurisdiction, the installation must
conform to the Standard for Controls and Safety
Devices for Automatically Fired Boilers, ANSI/ASME
CSD-1.
