LOCATION & PLACEMENT
When installing the boiler or heater, consideration must be given to proper location. In addition to the following
requirements, the installation must adhere to all local or state code requirements.
1. The unit should be leveled.
2. Minimum clearance for hot water pipes and venting from combustible material is 6 inches.
3. The boiler/heater must not be installed on carpeting or other combustible flooring.
4. The unit is for alcove installation on non-combustible floors only. The minimum clearance for
combustible material:
Minimum Clearance A-035 A-050 A-070 A-097 A-120 A-140
Back & Side Walls 24 24 24 24 24 24

5. The heater/boiler must be installed so that it can be serviced without removing the heater/boiler or any
surrounding structure. The minimum space required in front of the boiler to allow removal of the burner
is:
Minimum Clearance A-035 A-050 A-070 A-097 A-120 A-140

Dimensions in Inches
6. A hot water boiler installed above radiation level must be provided with a low water cutoff device either
as a part of the boiler or at the time of boiler installation.
7. The boiler/heater shall be protected from freezing. Heat exchangers damaged by freezing shall not be
considered for warranty.
8. The unit must be located where condensation or leakage from the heat exchanger or connections can
be drained and will not result in damage to the adjacent area or to lower floors of the structure. If this
cannot be avoidable, use of an adequately drained catch pan is recommended. The pan must not
restrict combustion air flow to the burner.
9. The boiler/heater must be installed such that the gas ignition system and other electrical components
are protected from water (dripping, spraying, rain, etc.) during operation and service.
Maintain the area surrounding the heater/boiler clean and free of combustible
materials, gasoline, and other flammable liquids or vapors. The heater/boiler should
never be covered.
COMBUSTION AIR REQUIREMENTS
The boiler/heater room must be provided with
TWO
openings to assure adequate combustion air and proper
ventilation. One opening should be 6 to 12 inches above the floor and the other 6 to 12 inches below the ceiling,
preferably on opposite walls. The size of each opening will vary based on whether the air is taken from inside or
outside the building, and with the input rating of the boiler/heater.
The make-up air must be sized for the total BTU per hour demand of ALL gas fired or
air using appliances served by these openings.
