WARNING
If you do not follow these instructions exactly,
a re or explosion may result causing property
damage or personal injury.
DANGER
Do not install boiler where gasoline or other
ammable vapors or liquids, or sources of
hydrocarbons (i.e. bleaches, cleaners, chemicals,
sprays, paint removers, fabric softeners, etc.) are
used or stored.
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
DOES NOT warrant failures caused by mis-sized
boiler applications. DO NOT oversize the boiler to
the system. Modular 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. Appliance is design certied 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 1 for minimum listed
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.
D. Install on level oor. For basement installation provide
solid base such as concrete, if oor is not level or if
water may be encountered on oor around boiler. Floor
must be able to support weight of boiler, water and all
additional system components.
E. Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
I. Pre-Installation
F. 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 or Propane Installation Code,
CAN/CSA-B149.1.
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]
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 unconned
space.
b. If result is less than 50 ft³ per 1,000 Btuh, space
is considered a conned 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
rating of 1 perm or less with openings gasketed
and sealed, and;
b. Weather-stripping has been added on openable
windows and doors, and;
c. Caulking or sealants applied in joints around
window and door frames, between sill plates and
oors, between wall-ceiling joints, between wall
panels, at plumbing and electrical penetrations,
and at other openings.
5. For boiler located in an unconned space in a
building of other than unusually tight construction,
adequate combustion and ventilation air is normally
provided by fresh air inltration through cracks
around windows and doors.
