Proximity of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,
parked vehicles, cranes and any other possible obstruction or hazard must be evaluated.
It is recommended that Protective Guard JS-0502-UR-GK be installed on any heater mounted
with less than 8 feet from floor to bottom of heater (See Accessories - Page 42).
6A. SERVICE CLEARANCE: The lower 'jaw' of the burner cabinet swings down to provide
convenient service access to burner components. Provide 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.

GUIDELINE MOUNTING HEIGHTS are typical to provide optimum comfort in general space
heating applications. Variance from these typical heights can occur in some applications:
Higher mounting height due to structure or application requirements
For 'area' or 'spot' heat, or in areas with greater infiltration rates (near overhead doors,
etc) where more intense heat is needed to provide better comfort then lower mounting
heights are recommended (minimum 8 ft [2.4 m] mounting height)
It is recommended that Protective Guard JS-0502-UR-GK be installed on any heater
mounted with less than 8 feet from floor to bottom of heater (See Accessories - Page 42)
