6. PRE INSTALLATION SURVEY

Carefully survey the area to be heated. It is recommended that a full heating design including

heat loss calculation be conducted on the structure or area to be heated. Heater sizing, quan-

tity, and placement must consider available mounting height, sources of greatest heat loss.

The certified clearances to combustibles must always be maintained with respect to stored ma-

terial, moveable objects (vehicles, lifts, overhead doors, etc), sprinkler system heads, furniture

and draperies, and other obstructions at the site. Consideration must also be given to vent

placement and the allowable length of vent . (see section 11, page 19)

Installation must conform with all local, state, provincial and national code requirements includ-

ing the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation code

in Canada, for gas burning appliances and equipment. The latest edition Electrical Code ANSI/

NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.

The heating system must have gas piping of the correct diameter, length, and arrangement to

provide adequate fuel supply and function properly. A dimensioned layout drawing is advised.

7. MOUNTING CLEARANCES

This heater must be mounted wit h at least the minimum clear ances between the heater and

combustibles as shown in FIG-1, TABLE 1, Pages 8 & 9. It is the installer’s responsibility to

ensure that building materials with a low heat tolerance which may degrade at lower

temperatures are protected to prevent degradation. Examples of low heat tolerance ma-

terials include vinyl siding, fabrics, some plastics, filmy materials, some coatings and

laminated finishes, etc.

Ensure adequate clearance around the air intake at the burner to allow sufficient com-

bustion air supply to the heater.

Proximity of lights, sprinkle r heads, overhead doors, storage areas , gas and electric al lines,

parked vehicles, cranes and any other possible obstruction or hazard must be evaluated.

Place the heater so as not to c ause a hazard to a wall, floor, shelving, curtains, furni ture, or

door when open, or impede the free movement of people.

8. SERVICE CLEARANCE: The lower ‘jaw’ of the burner c abinet swings down to provide con-

venient service access to burner components. Pr ovide a minimum clearance from any wall or

obstruction of 6 inches (15 cm) to the access end of the burner housing, and a minimum of 24

inches (61 cm) to any ONE side to allow burner service. (see Figure 2 below)

The minimum clearances to combustibles must always be maintained
