VI. Pre-Installation and Mounting
A. General Installation
1. Installation must conform to the requirements of
the authority having jurisdiction or, in the absence
of such requirements, to the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, and/or Natural Gas
and Propane Installation Code, CAN/CSA B149.1.
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.
2. Provide clearance between appliance jacket panels
and combustible material in accordance with local
fire ordinance. Refer to Table 5 for recommended
service clearances. Recommended service
clearances may be reduced but should not be less
than the clearance to combustibles.
3. Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during operation and
service (circulator replacement, condensate trap,
control replacement, etc.).
4. Provide combustion and ventilation air in
accordance with applicable provisions of local
building codes, or: USA - National Fuel Gas Code,
ANSI Z223.1/NFPA 54, Air for Combustion and
Ventilation; Canada - Natural Gas and Propane
Installation Code, CAN/CSA-B149.1, Venting
Systems and Air Supply for Appliances.
5. The appliance should be located so as to minimize
the length of the vent system. Ensure air intake
pipe termination is away from areas that may
contaminate the combustion air (see Table 4). In
particular, avoid areas near chemical products
containing chlorines, chlorofluorocarbons, paint
removers, cleaning solvents, and detergents. Avoid
areas containing saw dust, loose insulation fibers,
dry wall dust etc.
6. This appliance must not be installed in a room
under negative pressure. An equipment room
under negative pressure conditions could deplete
the combustion air supply to the appliance and
cause leakage of flue gas from the venting system.
a. Direct vent installation is not complete without
screwing down the front door for a proper seal
of the combustion air system.
!
Apply supplied dielectric grease to the gasket
inside the vent connector. Failure to apply the
grease could result in flue gas leaks during vent
pipe installation or gasket deterioration due to
condensate exposure.
Adequate combustion and ventilation air must
be provided to assure proper combustion. Install
combustion air intake using the methods in this
manual.
Installation of this appliance should be undertaken
only by trained and skilled personnel from a
qualified service agency. Follow these instructions
exactly. Improper installation, adjustment, service,
or maintenance can cause property damage,
personal injury or loss of life.
Do not change or modify any accessories or parts
or jump-out any safety limit devices.
Due to the low water content of the appliance,
mis-sizing with regard to the heating or hot water
system load will result in excessive cycling and
accelerated component failure.
Thermal Solutions DOES NOT warrant failures
caused by mis-sized appliance applications. DO
NOT oversize the appliance to the system. Multiple
unit installations greatly reduce the likelihood of
oversizing.
Avoid operating this appliance in an environment
where sawdust, loose insulation fibers, dry wall
dust, etc. are present. If operated under these
conditions, the burner interior and ports must
be cleaned and inspected daily to insure proper
operation.
Ensure all labels on the product are fully visible
at all times for the purpose of maintenance and
inspections.
