Clearance To Combustibles
A general clearance of 18” (0.5 m) in every direction is recommended (for servicing only) around each
burner to ensure adequate air flow in and around the Heating System.
In addition to this it is very important to observe the minimum clearance to combustibles at all
times to avoid any possibility of property damage or personal injury.
WARNING
•Clearances as marked on the heater body must be maintained from vehicles parked beneath. Signs
should be posted identifying any possible violation of the clearance distances from the heater in all
vehicle areas.
•Maximum allowable stacking height in storage areas should be identified with signs or appropriate
markings adjacent to the thermostat or in a conspicuous location.
Table 2 lists the minimum clearance to combustible materials for various installation configurations. Note
that standard clearances also apply to installation above T-bar ceilings and above decorative grills.
Additional clearance may be required for glass, painted surfaces and other materials which maybe
damaged by radiant or convective heat.
Combustible materials are considered to be wood, compressed paper, plant fibres, plastics, Plexiglas or
other materials capable of being ignited and burned. Such materials shall be considered combustible
even though flame-proofed, fire-retardant treated or plastered.
Elbows and U-bends are un-heat treated aluminized material and are installed with reflectors. Reflector
miter kits are available for U-bends and elbows.
Adequate clearance to sprinkler heads must be maintained.
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room
temperature. Building materials with low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply,
etc…) maybe subject to degradation at lower temperatures. It is the installer’s responsibility to assure
that adjacent materials are protected from degradation.
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. Page 10 shows minimum clearance to combustible materials.
Note 1:
Bottom Shields are approved for all burner sizes. The “below” clearance (dimension C in
Table 2) may be reduced by 25% when an approved Bottom Shield is used.
Caution: In all cases, the minimum hanging height from the floor shall be 8’

Installation Sequence
Figure 3: General Overview of Installation
A general ordered sequence for installation is provided below for reference.
H ANGERS I NSTALLATION
•Suspension mechanism must allow for lateral tubing expansion. A minimum 12" length welded
link chain with a working load limit of at least 200 lbs. is recommended (refer to Figure 4 for
more details). SRP recommends and make available “quick links” for connecting chain. If
any open ended “S” hooks and turnbuckles are used, the open ends must be closed to avoid
unhooking chain with inadvertent contact.
•Locate hanging chain at predetermined suspension points in the structure. It is required that the
first 2 hangers be about 8' to 9'. Thereafter, 10' apart on average is acceptable for the remainder
of the heat exchanger. At no time should hangers be more than 12' apart, (see Figure 5).
•Each hanging point must hold a minimum of 200 pounds
•Heater must fire horizontally

•Tighten the cradle loops of the first hanger with the “J-Bolt” found in the burner box, to snugly
hold the combustion tube from rotating see Figure 8.
Note: For all coupling joints, ensure that the tube joint is in the center of the coupling
length, and that the overlap joint of the coupling is above the centerline of the tube. Also
ensure that the weld seam on ALL tubes is facing down.
Note: In order to obtain smoothly sealed coupling liners, tighten each of the coupling
bands progressively and alternately. Tightening one band completely before the other may
result in an undesirable wrinkle in the liner. Be sure not to over torque the coupling.
(Torque coupling to 15-25 lbf-ft).
Figure 8: “J” Bolt and Coupling Installations
•Continue placing tubes, couplings and reflectors to complete the heater assembly. Ensure heat
exchanger sections line up straight. Couplings should be tightened as heat exchanger is placed,
since it is more difficult to do so once the reflector is in position.
