CAUTION: FIRE OR EXPLOSION HAZARD
Maintain clearance to combustible constructions as further specified in this manual. Failure
to do so could result in a serious fire hazard. Heaters should not be located in hazardous
atmospheres containing flammable vapors or combustible dusts. Signs should be provided in
storage areas specifying maximum safe stacking height.
CAUTION: MECHANICAL HAZARD
This equipment expands and contracts with each operating cycle. The gas connection,
suspension hardware and the installation itself must safely allow this movement. Failure to
do so could result in serious fire or explosion hazard.
CAUTION: FIRE OR EXPLOSION HAZARD
This heater is equipped with an automatic ignition device. Do not attempt to light the burner
by hand. Failure to comply could result in a serious fire and personal injury hazard.
CAUTION: MECHANICAL HAZARD
Do not use high pressure (above 1/2 psi) to test the gas supply system with the burners
connected. Failure to do so could result in damage to the burner and its control components
requiring replacement.
CAUTION: SERVICE LIFE RISK
Do not install equipment in atmospheres containing halogenated hydrocarbons or other
corrosive chemicals. Failure to do so may lead to premature equipment failure and
invalidation of the warranty. Additionally, it is recommended that the equipment be installed
with a slope downward and away from the burner of ¼" in 10' to allow start-up condensate
drainage.

Note:
-Baffles are always placed in the last section of radiant tube except for the 100,000 BTU Burner.
-Baffles are either aluminized or stainless steel sections 6' long.
-When only 6' is required (80,000 BTU), an aluminized steel baffle is installed.
-When 12' is required (40,000 or 60,000 BTU) the aluminized steel baffle is lengthened forward
(toward the burner) with a 6' stainless steel section.
-In the case of a 100,000 BTU system, place 4' sections of baffle in the end of each of the last 3
10'sections of tube.
Part numbers for reference are:
CT026 Baffle 4' long aluminized steel.
CT007 Baffle 6'long aluminized steel.
CT006 Baffle extension, 6' long stainless steel.
Insert (may be a factory installed, CHECK FOR ORIENTATION)
To further improve heat distribution along the length of the heater, two stainless inserts may be installed
at factory, check for correct orientation. The inserts will reduce heat output in the first tube, which results
in more heat release in the latter part of the heat exchanger. (See Figure 3)

Clearance to Combustibles
A general clearance of 18” (0.5 m) in every direction is recommended for servicing only around each
Burner, Vacuum Pump, and End Vent Cap air supply (at the far end of each Radiant Branch) also 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 2lists 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 typically installed without 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.
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.
Note 2:
Reduced clearances downstream from the burner are approved for all configurations. Dimensions “B”,
“C”, and “D” in Table 2can be reduced for locations 25' (7.6 m) or more downstream from a burner,
before the next burner, maximum reduction is 50%

Installation
Installation Sequence
Generally, there is no unique sequence for installation of the burner or heat exchanger. A review of the
job site will usually indicate a logical installation order. However, time and expense can be saved if
installation is begun at the most critical dimension, watching for interference from overhead doors,
cranes, auto lifts etc. Figure 4 to Figure 6provides a general overview of the components utilized in the
installation, as well as their general relationship.

Installation
A general ordered sequence for installation is provided below for reference.
Figure 7: General Overview of Installation
HANGERS INSTALLATION
Suspension mechanism must allow for lateral tubing expansion. A minimum 12" inch length
welded link chain with a working load limit of at least 200 lbs. is recommended (refer to Figure
8for 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' away. Thereafter, 10' apart on average is acceptable for the
remainder of the heat exchanger. At no time should hangers be more than 12' apart, (seeFigure 9).

TUBE INSTALLATION
Always use all the hangers supplied. As a rule the combustion tube (first tube) utilizes 2 hangers
and thereafter 1 hanger per 10' section. It is required that the first hanging point be 2"to 8"
from the burner mounting flange, and tube weld seam must face down, refer to Figure 10for
more details.
Figure 10: Installation of First section of Flanged Tube
For all remaining tubes, fit the end of the tube with a coupling refer toFigure 11, (the coupling
should be loose).

Installation
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 12.
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 (refer to Figure 12).Be sure not to over torque
the coupling. (Torque coupling to 15-25 lbf-ft).
Figure 12: “J” and Coupling Bolt 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.

HEATER AND BAFFLE INSTALLATION
Locate the burner gasket provided, bolt the burner in place on the tube flange with provided
hardware. Burner must never be installed in a tilted position. The sense electrode of the burner
cup should be in the 12 o’clock position (Figure 13).
Figure 13: Burner Gasket Installation
If required for your heater model (refer to Table 1), install the baffle at the end of the heat
exchanger. The small tab on the baffle is folded over the end of the tube and clamped in place by
the vent connector and vent system, refer to Figure 14.
Note: Baffles are always placed at the end of the last heat exchanger tube length, with the
exception of the special configuration 205,000 BTUH with a 50' tube length, refer to
Figure 3 for more details.
Note: Baffles are either one or two sections (each section is 6' in length). Multiple sections are
simply clipped together. Where stainless and aluminized sections are supplied, always
place the stainless steel section closest to the burner. The easiest installation method is to
pull the baffle through the tube using a long wire.
