Safety Information
Safety Information
The heater you have purchased as designed, first of all, to be safe. Ho ever, since this
heater burns propane, safety precautions are necessary for the safe and reliable operation of
this product. Throughout this guide, this important safety information ill be placed in
special arning boxes.
Warning: Never Restrict Access to the Controls
Never prevent access to the controls of the heaters of an
operating heater such as by blocking access panels and
doors ith cargo.
Warning: Use Propane Only
This heater is designed to operate on propane vapor at 11
inches of ater column only. Do not attempt to use
anything else as fuel since fire or explosion may result.
Warning: Do Not Bypass or Remove Safety Equipment
Although e understand temporary measures must
sometimes be made to save a load, bypassing any safety
device may result in fire or explosion. For your safety, do
not temporarily bypass any safety equipment, and if you do,
please fix these temporary measures as quickly as possible.
Warning: Exhaust Gases
Do not operate the heater hile the trailer is in an enclosed
area. This heater, like all heaters that run on fossil fuel,
produces exhaust containing carbon monoxide. This gas can
build up in enclosed areas causing illness or death.
Warning: Do Not Enter Trailer while Smoking
Do not enter the trailer hile smoking. It is possible if
safety features are bypassed or the heater is seriously
damaged for propane to build up in the cargo area. As a
result, never enter the cargo area ith an ignition source
or create an ignition source in the cargo area until it has
been properly vented. Furthermore, never enter the trailer
or stand near the trailer if you smell gas.
As al ays, apply common sense. If you’re not absolutely sure it’s safe then don’t do it.

Chapter 1 Introduction to Heater
Introduction to Heater
The catalytic heater you have purchased is a thermostatically controlled flameless
propane heater designed for heating cargo. These heaters have pilot light to preheat the
catalyst hen the heater is first lit but, once lit, the pilot light is shutoff and the heater
becomes flameless. The heater maintains the temperature of your cargo by s itching
bet een t o levels of heat output: a lo heat output and the full 18000 BTU/hr heat
output.
Your heater is one of t o models, either the CAT-700 or the CAT-900. Both models
share the same basic heater but differ in the number and size of the propane fuel tanks
they can carry. The CAT-700 stores a single 20lb propane bottle in the base hile the
CAT-900 stores t o 20 or 30lb propane bottles.

Chapter 2 Quick Start Guide
Quick Start Guide
Please read the important safety information on page ii if you haven’t already done so.
This guide assumes the heater has already been installed. For installation instruction
please go to chapter 5 (page 12).
For Instructions
On Running the Heater..........................................................................See Page 3
On Running the Heater for the first time in a few months.................See Page 5
2.1 Normal Operation
These instructions are for the day to day use of the heater. A shortened version of these
instructions can be found on the side of the heater.
2.1.1 Lighting the Heater
1) Check fuel system and turn on propane
Check that the propane tank(s) are not empty and are securely mounted in the base of
the heater. Check that the gas lines and fittings bet een the propane tank(s) and the
heater are tight and undamaged. Turn on the valve on the propane tank(s).
2) Set the thermostat to the maximum value and main control dial to PILOT
3) Light the pilot light
Push and hold the small red knob on the brass in and push the red button on the spark
igniter in once a second until the pilot light ignites. If the pilot light does not ignite
ithin 15 seconds, release the red knob on the brass valve to stop the flo of gas.
4) Wait for the catalytic pad by the pilot light to warm up.
Wait approximately one minute until a dull red glo appears on the catalytic pad near
the pilot flame.
5) Push down main control dial and wait for warm area on catalytic pad to
spread behind the themocouple.
Push do n the main control dial (currently in the pilot position) to provide additional
propane to the catalytic pad and allo the arm area to gro until it reaches the
thermocouple. This usually takes approximately one minute.
6) Turn the main control to ON
Turn the main control to ON and after 30 to 60 seconds extinguish the pilot light by
releasing the brass knob. Before you extinguish the pilot light, you ill probably see
ripples of flame travel across the pad as the pad heats up.
7) Wait for the heater to warm up. Wait 5 to 10 minutes for the red glow to
spread over the catalytic pad.
Check that no flames are visible inside the heater. Be sure to check the metal frame
around the perimeter of the catalytic pad. The heater should not be used if any flames
are visible.

Chapter 2 Quick Start Guide
) Set the heater to the desired temperature and secure into the trailer.
Set the heater to the desired temperature (HI is approximately 90 hile LO is
approximately 50). Secure the heater into the trailer and place the vent tube through
the hole in the floor.
2.1.2 Mounting the Heater
WARNING: Take care hen mounting the heater as failure to mount the heater
securely, failure to install the vent tube, or preventing access to the controls in
either the top and bottom of the heater are serious safety hazards.
The heater must be mounted securely to the trailer so that it can remain in place both
during normal operation and during accidents such as trailer tip-overs and roll-overs.
In additional, the heater must never be mounted in a ay that prevents access to the
controls in either the top or the base of the heater. You have three options for
mounting the trailer:
Wall Brackets
All heaters can be mounted to Elston-supplied all mount brackets. To attach
the heater to these brackets, first roll the heater up to the all brackets so that
the bottom bracket on the heater lines up ith the bottom bracket on the all.
Next slide back the heater until the bottom lip on the heater bracket is behind
and belo the bottom edge of the bracket on the all. Once this is in the
correct location it should no longer be possible to grab the handle at the top
and pivot the heater unto the heels ithout meeting resistance from the all
bracket. After that, slide the heater left or right as necessary so that you can
slide the bracket ith the ing nuts at the top of the heater into the bracket on
the all. Once that bracket is in position, tighten the ing nuts to finish
securing the heater to the all.
Adjustable Mount
As an optional accessory, Elston offers an adjustable mount that allo s you to
secure the heater ithout a pre-installed mounting bracket. To secure the
heater ith the adjustable mount, roll the heater against the all in the area
that is marked for the heater (There should be a small hole in the floor there
for the vent pipe.) Once the heater is in place, turn the handle on the front to
raise the upper pad until it presses against the ceiling firmly. When the heater
is secured, pulling on the handles firmly ill not dislodge the heater.
Customer Solutions
Your organization may have other approved methods for securing the heater.
Please check ith the person responsible for this ithin your company.
Whatever setup you use, you must not obstruct the inlet or outlets of the
heater shell or use materials, such as most types of nylon strapping, against
the shell of the heater that are degraded by repeated exposure to temperatures
up to 250F.
Once the heater is secured to the all, install the tube on the right side of the base of
the heater into the provided hole in the floor. This tube must be installed as it is a
4

Chapter 2 Quick Start Guide
safety device that prevents a leak in the fittings in the base of the heater from causing
a gas build up in the cargo area of the trailer.
2.1.3 Shutting Down the Heater
1) Turn the main control dial to OFF.
2) Close valves on the propane bottle(s)
3) Allo heater to cool for 5 minutes before moving or attempting to relight.
2.2 Running the Heater After It has Set Awhile
Please follo these instructions hen lighting the heater for the first time this heating
season or hen the heater hasn't been run for a fe months. Operation of the heater is the
same as above in section 2.1 except for the lighting instructions.
When the heater has set for a fe months it may be more difficult to light than normal.
This is especially common hen the heater has been stored uncovered and exposed to
significant quantities of dust as some types of dust reduce the effectiveness of the
catalytic pad. This effect is generally temporary and ill largely disappear after the heater
has ran at full po er for an hour.
1) Inspect the heater for damage and debris
Check the propane system for damage including cracked hoses, orn o-rings in the
pilot light valve and tank fittings, and damaged tubing and replace any damaged
components. Check inside the heater for debris especially around the catalytic pad
and remove all debris present.
2) Check fuel system and turn on propane
Check that the propane tank(s) are not empty and are securely mounted in the base of
the heater. Check that the fittings bet een the propane tank(s) and the heater are tight
and undamaged. Turn on the valve on the propane tank(s).
3) Set the thermostat to the maximum value and main control dial to PILOT
4) Light the pilot light
Push and hold the small red knob on the brass in and push the red button on the spark
igniter in once a second until the pilot light ignites. If the pilot light does not ignite
ithin 15 seconds, release the red knob on the brass valve to stop the flo of gas.
5) Wait for the catalytic pad by the pilot light to warm up.
Wait approximately one minute until a dull red glo appears on the catalytic pad near
the pilot flame.
6) Push down main control dial and wait for warm area on catalytic pad to
spread behind the themocouple.
Push do n the main control dial (currently in the pilot position) to provide additional
propane to the catalytic pad and allo the arm area to gro until it reaches the
thermocouple. This usually takes approximately one minute.
7) Turn the main control to ON
Turn the main control to ON and after 30 to 60 seconds extinguish the pilot light by
releasing the brass knob. Before you extinguish the pilot light, you ill probably see
ripples of flame travel across the pad as the pad heats up.
) Wait for the heater to warm up.
Wait 5 to 10 minutes for the red glo to spread over the catalytic pad. Check that no

Chapter 4 Troubleshooting
Troubleshooting
If this guide doesn’t fix your problem please contact the company here you purchased
the heater. If you are unable to contact them or you need additional help, please contact
Elston Manufacturing at 1-800-845-1385.
Caution: For your safety, the propane should al ays be turned off hen
troubleshooting this product except hen required to test the function of the
heater.
What is wrong with the heater?
A. Pilot light doesn't light
B. Pilot light does not create a hot spot on the catalytic pad
C. Pad never gets hot hen lighting heater
D. Pad takes a long time to get to full temperature
E. Heater goes out after running at least 30 minutes but before the tank is empty
F. Flames are visible after the pilot light is extinguished
Problem A: Pilot Light Doesn't Light
Cause: Propane tank is empty
Makes sure the propane tank is not empty. If you have a CAT-900, check that the tank
selection lever is pointing to ard a non-empty tank. When the lever is pointing to ard a
tank and the valve for that tank is on, you should see green in the indo on the
regulator hen the selected tank contains propane.
Cause: Excess flow valve was triggered
If the valve on the tank is opened quickly, the initial pulse of gas into the gas lines for the
heater may trigger the excess flo valve built into the heater hich restricts gas flo to a
very lo value. Close the tank valve(s) and slo ly open them to reset the excess flo
valve.
Cause: Problem with push button sparker
Check that the ire on the back of the push button sparker is attached and the spark is not
jumping to the frame of the catalytic pad. If the spark is jumping to the frame of the
catalytic pad, loosen the t o scre s attaching the pilot light assembly and slight the
assembly slightly a ay from the catalytic pad hile keeping it at the same angle to the
pad and retighten the scre s.
Cause: Pilot light orifices are plugged
8

Chapter 4 Troubleshooting
The gas for the pilot light travels through 2 sets of orifices, either of hich can block the
flo of gas. The first orifice is in the pilot light valve block and the second is in the pilot
light assembly. It is also possible that some debris, such as a spider eb or dead bug, is in
the channel in the pilot light and blocking the flo of gas to ard the spark.
Problem B: Pilot Light Does Not Create a Hot Spot on the Catalytic Pad
Cause: Excess flow valve was triggered
If the valve on the tank is opened quickly, the initial pulse of gas into the gas lines for the
heater may trigger the excess flo valve built into the heater. Close the tank valve(s) and
slo ly open them to reset the excess flo valve.
Cause: Pilot light orifices are partially plugged
The gas for the pilot light travels through 2 sets of orifices, either of hich can block the
flo of gas. The first orifice is in the pilot light valve block and the second is in the pilot
light assembly. It is also possible that some debris, such as a spider eb or a dead bug, is
in the channel in the pilot light and blocking the flo of gas to ard the catalytic pad.
Cause: Position of the pilot light assembly is incorrect
The large flame of the pilot light should touch or nearly touch the pad near the edge of
the thermocouple plate. The pilot light can hit the plate but at least half the flame must
touch the pad. If more than this portion of the pilot light hits the thermocouple plate,
loosen the t o scre attaching the pilot light assembly and move it to the correct
location. When retightening the assembly into place, make sure that the sparker is more
than 1/4” from the frame of the catalytic pad to prevent the spark from jumping to an
incorrect location and preventing you from lighting the pilot light.
Problem C: Catalytic Pad Never Gets Hot When Lighting Heater
Cause: Temperature is not low enough for thermostat to turn heater completely on
If the temperature here you are lighting the heater is above 60 F, the thermostat may not
turn on the full flo of gas even hen the thermostat dial is set to HI. Move the heater to
a cooler location or cool the thermostat probe ith an ice cube and retry the lighting
process.
Cause: Catalytic pad was not sufficiently prewarmed earlier in the lighting process
The pilot light must get at least a small area of the catalyst arm enough to activate the
catalyst and get the thermocouple arm enough to allo gas to flo through the control
before the pilot light is extinguished. If either (or both) of these doesn't happen, the safety
system on the heater ill shut it do n. If you haven't already done so please try lighting
the heater follo ing the instructions found in this manual.
When the extended lighting instructions don't ork, this problem is typically caused by
one of four reasons:
9

Chapter 4 Troubleshooting
1. The pilot light as not left on long enough
Make sure that you leave the pilot light on for at least 60 seconds bet een each
step to allo the heat to penetrate into the pad and spread a little bit.
2. The thermocouple is out of position
If the thermocouple is more than a ¼” from the catalytic pad or tilted at an angle
(more than a fe degrees), the heat from the pad may fail to get the thermocouple
hot enough to allo gas to flo through the control. If the thermocouple is out of
position, remove the bottom grill on the heater and loosen the scre holding the
thermocouple and adjust the thermocouple so the plate is parallel to the pad and
1/8” from the pad.
3. The pilot light is too small
Refer to the tips in problem B above for recommendations.
4. The thermocouple has failed
If none of the above recommendations help and the pad remains glo ing by the
pilot light hen the control is pushed do n in the PILOT position and the pilot
light is temporarily extinguished, the thermocouple has failed and needs to be
replaced.
Cause: Gas supply problems
If the gas supply to the heater is partially restricted the heater ill only be able to get
enough propane for the pilot light. Check that the selection lever is pointing to ard a full
tank and tank valve is open at least a full turn. If you have the tools, check that the heater
is receiving 11” ater column of propane vapor throughout the lighting process.
Problem D: Catalytic Pad Takes a Long Time to Get to Full Temperature
Cause: Catalytic pad was not sufficiently prewarmed earlier in the lighting process
If the area of the catalyst arm enough to activate the catalyst is too small it ill take a
long time for the pad to get to full temperature. If you haven't already done so please try
lighting the heater follo ing the instructions found in this manual.
When the extended lighting instructions don't ork, this problem is typically caused by
one of three reasons:
1. The pilot light as not left on long enough
Make sure that you leave the pilot light on for at least 60 seconds bet een each
step to allo the heat to penetrate into the pad and spread a little bit.
2. The pilot light is out of position
If the pilot light hits the plate on the thermocouple instead of hitting the catalytic
pad, the pad ill barely heat up. Adjust the postion of the pilot light assembly
and/or the thermocouple so that the large flame of the pilot light touches or nearly
touches the pad near the edge of the thermocouple plate.
3. The pilot light is too small
Refer to the tips in problem B above for recommendations.
10

Chapter 4 Troubleshooting
Cause: Catalytic pad is worn out
If the catalytic pad is covered in too much dust the propane is unable to effectively
interact ith the catalyst. Gently blo any dust off of the pad being careful not to damage
the pad. If that doesn't ork, the pad may be orn out and need to be replaced. It takes a
fe years for a pad to ear out and the typical life span is around ten years.
Problem E: Heater Goes Out After Running at Least 30 Minutes
Cause: Catalytic pad is worn out
If the catalytic pad is covered in too much dust the propane is unable to effectively
interact ith the catalyst. Gently blo any dust off of the pad being careful not to damage
the pad. If that doesn't ork, the pad may be orn out and unable to remain hot enough
hen the heater is on standby. A orn out pad ill be nearly hite and needs to be
replaced.
Cause: The thermocouple is out of position
If the thermocouple is more than a 1/8” from the catalytic pad or tilted at an angle (more
than a fe degrees), the thermocouple may not remain hot enough hen the heater is on
standby to allo gas to flo through the control. If the thermocouple is out of position,
remove the bottom grill on the heater and loosen the scre holding the thermocouple and
adjust the thermocouple so the plate is parallel to the pad and 1/8” from the pad.
Problem F: Flames are Visible after Pilot Light is Extinguished
Cause: Damage to catalytic pad or sealing cement
Use high temperature furnace cement to repair the damaged or missing sealant. If cement
has been lost from around a scre , retighten the scre before applying ne cement.

Chapter 5 Installation
Installation
Warning: Improper installation of this heater creates a substantial safety hazard
including the risk of property damage, fire, death.
Attention: Compliance ith local regulation is the responsibility of the installer.
Current regulations in your area may require that the installer of this heater or,
more likely, that the installer of the propane system fueling this heater meet
certain requirements and/or that the completed installation be inspected. If you
are unsure hat is required, please refer to the current regulations in your area
or speak ith the authority having jurisdiction before beginning installation.
5.1 Overview
These purpose of these instructions is to aid you in installing a fully functional heater that
is safe and secure under both normal condition and, as much as possible, during an
accident. Ho ever these instructions are not a substitute for personal kno ledge and
experience ith installing propane and/or electrical systems. Please do not install those
areas of the heater unless you have personal kno ledge and experience in these areas.
These instructions ere ritten ith the latest standards for the US in mind and are
intended to guide you in an installation that meets these standards. At the time of riting,
the latest standard as the 2008 edition of NFPA 58, the Liquefied Petroleum Gas Code
and part 393.77 of the Federal Motor Carrier Safety Administration rules. Ho ever, if the
regulations that apply in your area conflict ith these installation instructions the
regulations should al ays be follo ed instead.
Setup for these heaters is simple as they are designed to roll on and off cargo trailers and
van bodies to provide heat as needed but does require some setup ork on the trailers you
plan to use the heater in. The exact setup depends on if you are using the standard
mounting brackets or the optional adjustable mount.
5.2 Unpacking the Heater and Gathering Supplies
Parts Needed for Installation shipped with Heater:
•Roll on Heater
•Lo er all mount bracket
•Upper all mount bracket
Additional parts required:
•12 to 16 scre s or bolts appropriate for securing 1/8” thick steel to the trailer all
per set of mounting brackets
•Additional lo er and upper all brackets (optional)
12

Chapter 5 Installation
•Tape or paint for marking out the boundaries of the heater to ensure space remains
for heater after cargo is loaded (recommended)
5.3 Mounting
WARNING: Failure to mount the brackets for the heater securely or drill the hole
for the vent tube ill cause serious safety hazards hen the heater is operated.
Every trailer or truck body here you plan to use the heater ill need to be prepared for
use.
The primary consideration for the
placement of the heater is a position
against a all of the trailer that can easily
be left open for the heater after cargo is
loaded.
Setup for Standard Mounting Brackets
Install the lo er bracket on the all ith
the base of the bracket against the floor.
Attach the bracket to supports in the all
for maximum strength in a position here
the hole for the vent tube ill not have to
be drilled through one of the supports for
the trailer floor. Make sure the bracket is
firmed attached to all so that you ould
reasonable expect the bracket to bend
before pulling the scre or bolts out of the
all.
Install the upper bracket centered above
the lo er bracket at the location sho n in
Illustration 3 for your model. It should be
as firmly attached as the last bracket.
Next drill the 7/8” hole for the vent tube
for your model in the location sho n in
Illustration 4.
Once both brackets are
installed and the hole is drilled,
check that the heater fits on the
brackets.
Setup for Adjustable Mount
Drill the 7/8” hole for the vent
tube for your model in the
location sho n in Illustration
. Since no bottom bracket is
necessary for an adjustable mount, the hole just needs to be 8 1/4” a ay from the all.

5.4 Final details
It is recommended that you mark the
outline for the heater ith paint or
tape or similar to prevent cargo from
accidentally being placed here the
heater ill be mounted or here it
ould prevent access to the heater
controls. Illustration 5 sho s the
suggested reserved area for the
heater that allo s approximately
12” for access for the controls and
adequate space to open the door in
the base to access the tank shutoff
values and allo removal and
replacement of the tanks.
It is also recommended that a X-850
ventilator be mounted on the trailer
for proper ventilation.
Give the installation one final check to make sure nothing has been forgotten or
improperly completed. If everything looks good, the heater is ready to be test fired. For
instructions on firing up the heater for the first time please consult the quick start guide.
The installation is no complete and the heater can be placed in service.
