I. Pre-Installation
D. Provide clearance between boiler jacket and
combustible material in accordance with local fi re
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 fl oor. For basement installation provide
solid base, such as concrete, if fl oor is not level or if
water may be encountered on fl oor around boiler.
F. Install near outside wall for through wall venting.
Refer to Section V: Venting, for vent length limitations.

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.

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]
2. Determine Total Input of all appliances in space.
Round result to nearest 1,000 Btu per hour (Btuh).
3. Determine type of space. Divide Volume by Total
Input.

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 fi led
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.
Figure 2: Minimum Clearances to Combustible
Construction for Closet Installation
C. Appliance is design certifi ed for installation on
combustible fl ooring. The boiler must not be installed
on carpeting.
