I. Pre-Installation
F. Provide combustion and ventilation air in accordance
with applicable provisions of local building codes, or
National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air
for Combustion and Ventilation.
The following guideline is based on the National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
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. If result is greater than or equal to 50 ft³ per
1,000 Btuh, space is considered an unconned
space.
b. If result is less than 50 ft³ per 1,000 Btuh, space
is considered a conned space.
4. Determine building type. A building of unusually
tight construction has the following characteristics:
a. Walls and ceiling exposed to outside atmosphere
have a continuous water vapor retarder with a
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, ANSI Z223.1/NFPA 54.
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.

clearance from combustible material. Recommended
service clearance is 24 inches from left side, right
side and front. Service clearances may be reduced to
minimum clearances to combustible materials.

and service (circulator replacement, condensate trap,
control replacement, etc.).

WARNING
Boiler materials of construction, products of combustion and the fuel contain alumina, silica, heavy
metals, carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful substances which
can cause death or serious injury and which are known to the state of California to cause cancer, birth
defects and other reproductive harm. Always use proper safety clothing, respirators and equipment
when servicing or working nearby the boiler.
Failure to follow all instructions in the proper order can cause personal injury or death. Read all
instructions, including all those contained in component manufacturers manuals which are provided
with the boiler before installing, starting up, operating, maintaining or servicing.
Keep boiler area clear and free from combustible materials, gasoline and other ammable vapors or
liquids.
All cover plates, enclosures and guards must be in place at all times.
