I. Pre-Installation
WARNING
If you do not follow these instructions ex-
actly, a fire or explosion may result causing
property damage or personal injury.
DANGER
Do not install boiler where gasoline or other
flammable 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. Thermal Solutions 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 over-
sizing.
A.
Installation must conform to the requirements of the
authority having jurisdiction. In the absence of such
requirements, installation must conform to the Na-
tional Fuel Gas Code, NFPA 54/ANSI Z223.1, and/or
CAN/CGA B149 Installation Codes. Where required
the installation must conform to the standard for con-
trols and safety devices for automatically fired boilers,
ANSI/ASME CSD-1.
B.
Appliance is design certified for installation on combus-
tible flooring. Do not install boiler on carpeting.
C.
Provide clearance between boiler jacket and combus-
tible material in accordance with local fire 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. Rec-
ommended service clearance is 36" at rear of unit. Ser-
vice clearances may be reduced to minimum clearances
to combustible materials.
D.
Install on level floor. Floor must be able to support
weight of boiler, water and all additional system com-
ponents.
E.
Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
F.
Provide combustion and ventilation air in accordance
with sections 5.3 of the National Fuel Gas code,
ANSIZ223.1/NFPA 54, or sections 7.2, 7.3, or 7.4 of
CAN/CSA B149.1, Natural Gas and Propane Installa-
tion code, or applicable provisions of the local building
codes.
WARNING
Adequate combustion and ventilation air
must be provided to assure proper combus-
tion.
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 open-
ings 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 unconfined
space.
b. If result is less than 50 ft³ per 1,000 Btuh, space
is considered a confined 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
floors, between wall-ceiling joints, between wall
panels, at plumbing and electrical penetrations,
and at other openings.
