CAUTION: FIRE OR EXPLOSION HAZARD
Maintain clearance to combustible materials 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 EXPLOSIONS 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 ½ psi, 60 mbar)
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 atmosphere
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 downward slope, away from the
burner. The rate of declination should be ¼” (6mm) in height per 10’ (3m) in length to allow the start-up
condensation to drain.

When installing this appliance over 4500 ft. above sea level in Canada, the appliance must be properly de-rated
and installed according to local codes. In the absence of local codes the appliance must be de-rated in accordance
with the most recent CSA - B149 code. In the United States for installations over 2000ft above sea level the
appliance must be installed in accordance with the Current National Fuel Gas Code, ANSI Z223.1/NFPA 54. High
altitude conversion kits are available, contact manufacturer for more details.

Clearance to Combustibles
A general clearance of 18 (0.5 m) in every direction is recommended for servicing only around each Burner and
air supply (at the far end of each radiant tube). 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.
Table 1 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.
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 (i.e. plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to
degradation at lower temperatures. It is the installer’s responsibility to ensure that adjacent materials are
protected from deterioration.

Installation
Installation Sequence
Hangers Installation
•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. SRP recommends and make available “quick links” for
connecting chain. If any open ended turnbuckles are used, the open ends must be closed to avoid unhooking
chain with inadvertent contact.
Step 1:
Hang these about 100” apart.
100”
Figure 2: Hanger Installation options

Series AUXS & Series ATXS Page 9 LT363 Aug 13 2021
Tube Installation
Step 2-A:
Before installing the four U-Bolts, just ONE of the U-Bolts gets extra nuts, as shown here:
Thread the extra nuts upwards
(they don’t need to be tight for now)
Step 2-B:
Install Tubes and U-Bolts.
U-Bolt with extra nuts – close to Flange.
The nuts sandwich the Hanger Bracket as
pictured above.

Series AUXS & Series ATXS Page 10 LT363 Aug 13 2021
Step 3:
Orient the Tubes within the U-Bolts.
On the burner side, the distance between
the Flange and U-Bolt should be 8”
On the U-Tube side, the distance between
the Tube’s end and U-Bolt should be 10”
10”
Step 4:
8”
Fasten the remaining 8 nuts onto the U-Bolts – leave these
loose until the end!

Series AUXS & Series ATXS Page 11 LT363 Aug 13 2021
Baffle Installation
Step 5:
Install the Baffles: Pictured below is a bottom view of the heater.
•2 foot Baffle is isolated in the Flanged Tube (Combustion Tube)
•6 foot and 4 foot Baffle are linked together in the Non-Flanged Tube (Return Tube)
Bend Baffle Tab
over edge of Tube
at 6:00 position
Lock both Baffles together before inserting:
Align the little tabs and keyhole together at a 90 degree angle. Insert the tabs into the keyhole.
Rotate to 0 degrees, and then slide both Baffles into the Non-Flanged Tube.

U-Tube Installation
Reflector Installation
Step 6:
Attach Couplings and U-Tube together.
The Coupling has a tab inside to dictate the depth of the Tubes and U-Tubes.
Both edges of the Tube and U-Tube should be touching.
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 8). Be sure not to over torque the coupling. (Torque coupling to 15-25 lbf-ft).
Step 7:
Place Reflectors onto heater.
They’ll be loose for now, but these two pictures
depict how the Reflectors will be oriented
once they are fastened:

Series AUXS & Series ATXS Page 13 LT363 Aug 13 2021
Step 8-A:
Install the following components, 62” (middle) from the edge of the Reflector:
Qty 2 - CR004 Reflector Brackets
Qty 2 - CR009 Spring Clip
Qty 4 - CH044 Screw, 8-32 x 1-1/4
Hex Head, Roberston #2
Step 8-B:
Set the screws to a leave a gap of no more than 0.125”
62”

Series AUXS & Series ATXS Page 14 LT363 Aug 13 2021
Step 9:
Install the Inner End Cap with 6 screws, as pictured here:
End Cap with flanges on the inside (hidden).

Series AUXS & Series ATXS Page 15 LT363 Aug 13 2021
Step 10:
Fasten one Hanger to the Reflector, using the standard screws.
Fasten this
bracket only.
(This bracket is left free
for reflector expansion)
Step 10-A:
Ensure the Hanger Bracket is perpendicular to the
Reflector, and then follow these dimensions:
6”
3”

Series AUXS & Series ATXS Page 16 LT363 Aug 13 2021
Step 10-B:
Hold the Reflector tight to the bracket while fastening. Screw the bracket to the reflector.
Match the profile of the Reflector and Bracket as pictured:

Series AUXS & Series ATXS Page 17 LT363 Aug 13 2021
Step 11-A:
Orient the End Caps onto the Reflector.
Step 11-B:
Fasten the End Caps with a total of 12 standard screws.
End Cap with flanges on the outside

Series AUXS & Series ATXS Page 18 LT363 Aug 13 2021
Step 12:
Fasten the Hanger to the Reflector, using the standard screws.
*While fastening, hold the Reflector tight to the bracket.

Series AUXS & Series ATXS Page 19 LT363 Aug 13 2021
Step 13-A:
Attach the U-Tube End Cap to the U-Tube Reflector with 10 screws, as pictured here:
End Cap with flanges on the outside.
Step 13-B:
Install the Reflector onto the heater by overlapping the two reflectors.
2”
*Critical!
Before fastening in the next step, ensure that there is a 2” gap
between the U-Tube and End Cap.

Series AUXS & Series ATXS Page 20 LT363 Aug 13 2021
Step 14:
Use standard screws as shown, to fasten the Reflector,:
