CLEARANCES

ALL HEATERS

For clearances from combustible surfaces, see chart below. We require a minimal vertical clearance of three feet between the upper surface of the flue outlet to a non- combustible material.

MINIMUM CLEARANCES FROM COMBUSTIBLE CONSTRUCTION

INDOOR HEATERS

Top - 24"*Vent - 6"

Back - 24"

Right Side - 24"

Left Side - 24"

OUTDOOR HEATERS (926-1758)

Top - unobstructed

Back - 24"

Right side - 24"

Left Side - 24"

For servicing provide a front clearance as shown below Model 926/962-758/1826 - 24"

Model 2100-4001 - 48"

*Vent includes factory supplied drafthood and does not include field supplied vent systems above the draft- hood. On Models 2100-4001 drafthood is built into boiler.

For servicing, provide at least 24" in front of the heater on Models 926-1826 & 48" in front of the heater on Models 2100-4001 for burner tray removal, and at least 18" on the right side of the heater to inspect and delime the heat exchanger.

OUTDOOR HEATERS (MODELS 926-1758)

These heaters are design certified for outdoor installation,when equipped with the approved top desig- nated for outdoor use. Heaters must not be installed under an overhang of less than three (3) feet from the top of the heater. Three (3) sides must be open in the area undertheoverhang. Roofwaterdrainagemustbediverted away from the heaters installed under overhangs with the use of gutters.

WARNING: The heater shall not be located in an area where water sprinklers, or other devices, may cause water to spray through the cabinet louvers and into the heater. This could cause heavy internal rusting or damage some electrical components, and this would void the warranty.

Forced Air Inlet

 

Fig. #8245

The point from where the flue products exit the heater must be a minimum of four (4) feet below, four (4) feet horizontally from or one (1) foot above any door, window or gravity inlet to a building. The top surface of the heater shall be at least three (3) feet above any forced air inlet, or intake ducts located within ten (10 ) feet horizontally.

HIGH WIND CONDITIONS (OUTDOOR UNITS ONLY) In areas where high winds are frequent, it may be necessary to locate the heater a minimum of 3' from high vertical walls, or install a wind break so the heater

is not in direct wind current.

INDOOR HEATERS

The design is also certified for indoor installation when equipped with approved drafthood. Locate heater as close as practical to a chimney or gas vent.

COMBUSTION AIR (INDOOR UNITS ONLY)

The heater must have both combustion and venti- lation air. Openings must not be obstructed. Minimum requirements are as follows:

CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the heater and void the warranty.

1.Free combustion air 1 sq. in. per 1000 BTU input within 12" of the floor.

2.Free ventilation air 1 sq. in. per 1000 BTU input within 12" of the ceiling level.

NOTE: If the room the heater is installed in is located against an outside wall and air openings communicate directly with the outdoors, the openings may be 1/4 the size specified above (ANSI Z223.1/NFPA 54, latest edition)
