Series ETSV Infrared Heater
Two-Stage

LT284 Series ETSV 2Jan. 30, 2020
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 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.
CALIFORNIA PROPOSITION 65
This appliance, its related accessories and by-product of operation, contain chemicals known to the
State of California to cause cancer and birth defects or other reproductive harm. For more information
go to www.P65Warnings.ca.gov.

LT284 Series ETSV 3Jan. 30, 2020
WARNING - CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected to the venting system being
placed into operation could result in carbon monoxide poisoning or death. The following steps shall be
followed for each appliance connected to the venting system being placed into operation, while all other
appliances connected to the venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA
B149.1 and these instructions. Determine that there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause an unsafe condition.
3. As far as practical, close all building doors and windows and all doors between the space in
which the appliances(s) connected to the venting system are located and other spaces of the
building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any
exhaust fans, such as range hoods and bathroom exhausts, so they are operating at maximum
speed. Do not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance being inspected into operation. Adjust the
thermostat so appliance is operating continuously.
7. Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5
minutes of main burner operation. Use the flame of a match or candle.
8. If improper venting is observed during any of the above tests, the venting system must be
corrected in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or
Natural Gas and Propane Installation Code, CSA B149.1.
9. After it has been determined that each appliance connected to the venting system properly
vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers
and any other gas-fired burning appliance to their previous conditions of use.
WARNING
Certain materials or items, when stored under the heater, will be subjected to radiant heat and could be
seriously damaged. Children and adults should be alerted to the hazards of high surface temperatures
and should stay away to avoid burns or clothing ignition. Young children should be carefully supervised
when they are in the same space as the heater. Clothing or other flammable materials should not be
hung from the heater, or placed on or near the heater.
WARNING - RESIDENTIAL DWELLINGS
Certain materials or items, when stored under the heater, will be subjected to radiant heat and could be
seriously damaged. Children and adults should be alerted to the hazards of high surface temperatures
and should stay away to avoid burns or clothing ignition. Young children should be carefully supervised
when they are in the same space as the heater. Clothing or other flammable materials should not be
hung from the heater, or placed on or near the heater.
SAFETY FEATURES
This heater utilizes an airflow switch as blocked vent shut off system. This system is designed to
prevent the operation of the appliance if a fresh air supply is blocked or if the flue exhaust is blocked. If
this system fails to operate DO NOT ATTEMPT ADJUSTMENTS. Disconnect power to the appliance
and contact a qualified service person.

Installation Requirements
Clearance to Combustibles
A general clearance of 18” (0.5 m) in every direction is recommended for servicing around each Burner. This
ensures 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 below lists the minimum clearance to combustible materials for various installation configurations. Additional
clearance may be required for glass, painted surfaces and other materials which may be 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. NOTE: Sprinkler head heat fuse link performance may
alter with age.
The stated clearance to combustibles represents a surface temperature of 90°C (50°F) above room temperature.
Building materials with low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may become subject
to degradation at lower temperatures. It is the installer’s responsibility to ensure that adjacent materials are
protected from degradation.

Heater Mounting
The heater can be mounted in a variety of ways, using a combination of chains or mounting brackets. It is critical that
the heater is prevented from swaying and putting stress on the gas connection. Also, be sure to check local codes for
seismic bracing requirements for outdoor heating equipment.
Note: Minimum mounting height is 7’ in Canada and 8’ in the US.
Rigid Surface Mounting
In order to allow for lateral tubing expansion in the case of rigid mounting, the burner hanger must be free and the rest
of the hangers must be fixed, as outlined below.

Note: It is crucial to position the free hanger such that the heater may expand in the direction of the

Installation Instructions
Installation Sequence ETSV 40
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 beams etc.
It is RECOMMENDED to follow the assembly sequence shown in the following pages for free hanging installation.
