Clearance To Combustibles 

 

It is important to observe minimum clearance to combustibles at all times to avoid any possibility of 
property damage or personal injury.  Clearances must be maintained from vehicles parked beneath 
heaters.  Signs should be posted identifying any possible violation of the clearance distances from the 
heater in vehicle areas.  Also, maximum allowable stacking height in storage areas should be identified 
with signs or appropriate markings. Table 2 lists minimum clearance to combustible materials 
corresponding to the installation configuration. 

Approved reflector configurations include the standard 

(with or without decorative grille)

, the 45° tilt 

reflector, single and dual side extension shields, standard U tube mounting and opposite 45° U tube 
reflector mounting. 

Bottom shields are also approved.  The “below” clearance dimension for the horizontal configuration 

(dimension “C” in Table 2)

 may be reduced by 25% when an approved bottom shield is used. 

Reduced clearances downstream from the burner are approved for all configurations, except those with 
the U-bend.  Dimensions “B”, “C”, and “D” can be reduced by 50% for locations 25' feet or more 
downstream from the burner box. 

Elbows and U-bends are un-heat-treated aluminized material and are typically installed without 
reflectors.  Clearance to combustibles is 18" inches above and from the end in all cases.  When elbows 
or U-bends must be reflectored due to the proximity of combustible material, a 90 degree mitered 
reflector kit is available from your SRP dealer (part # CR039). Clearances in the case where mitered 
reflector kits are used are the same as the previous section of reflector.
