warnings in these sections. Installation, service and annual inspection of heater must be done by a contractor qualified in the installation and service of gas-fired heating equipment.

Read this manual carefully before installation, operation or service of this equipment.

This heater is designed for heating nonresidential indoor spaces. Do not install in residential spaces. These instructions, the layout drawing, local codes and ordinances, and applicable standards that apply to gas piping, electrical wiring, venting, etc. must be thoroughly understood before proceeding with the installation.

Protective gear is to be worn during installation, operation and service. Thin sheet metal parts,

FIGURE 1: Top and Bottom Panel Label Placement

including the aluminum reflector portion of the heater and the various venting components, ha

ve sharp edges. To prevent injury, the use of work gloves is recommended. The use of gloves will also prevent the transfer of body oils from the hands to the surface of the reflector.

Before installation, check that the local distribution conditions, nature of gas and pressure, and adjust- ment of the appliance are compatible.

For additional copies of the Installation, Operation and Service Manual, please contact Roberts-Gordon LLC.

SECTION 2: INSTALLER R ESPONSIBILITY

CAUTION

Product Damage Hazard

Do not use heater in area containing corrosive chemicals.

Refer to appropriate Material Safety Data Sheets (MSDS).

Failure to follow these instructions can result in product damage.

SECTION 2: INSTALLER RESPONSIBILITY

The installer is responsible for the following:

• To install the heater, as well as the gas and electrical supplies, in accordance with applicable specifications and codes. Roberts-Gordon recommends the installer contact a local Building Inspector or Fire Marshal for guidance.

• To use the information given in a layout drawing and in the manual together with the cited codes and regulations to perform the installation.

• To install the heater in accordance with the clearances to combustibles.

• To furnish all needed materials not furnished as standard equipment.

• To plan location of supports.

• To provide access to burners for servicing on all sides for burner removal.

• To provide the owner with a copy of this installation, operation and service manual.

•To never use heater as support for a ladder or

other access equipment and never hang or sus- pend anything from heater.

• To ensure there is adequate air circulation around

the heater and to supply air for combu lation and distribution in accordance with local codes.

• To safely and adequately install heater using

materials with a minimal working load of 75 lbs (33 kg).

• To ensure the heater is placed in a approved

application.

2.1 Wall Tag

A laminated wall tag is available for the heater as a permanent reminder of the safety instructions and the importance of the required clearances to combustibles. Please contact Roberts-Gordon or your ROBERTS GORDON

independent distributor to obtain the wall tag. Affix the tag by peeling off the backing of the adhesive strips on the rear surface and position the tag on a wall near the heater (e.g. thermostat or ROBERTS GORDON

A copy of the wall tag (P/N 91037912) is illustrated on the back cover. For an immediate solution, you may affix this copy on the wall near the heater.

Know your model number and installed configuration. Model number and installed configuration are found

stion, venti-

Controller).

on the burner and in the Installation, Operation and Service Manual. See Page 4, Figure 3 through Page 7, Figure 12. Write the proper clearance dimensions in permanent ink according to your model number and configuration in the open spaces on the tag.

2.2 Corrosive Chemicals

Roberts-Gordon cannot be responsible for ensuring that all appropriate safety measures are undertaken prior to installation; this is entirely the responsibility of the installer. It is essential that the contractor, the sub-contractor, or the owner identifies the presence of combustible materials, corrosive chemicals or halogenated hydrocarbons* anywhere in the premises.

* Halogenated Hydrocarbons are a family of chemical compounds characterized by the presence of halogen elements (fluorine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaning agents, solvents, etc. If these compounds enter the air supply of the burner, the life span of the heater components will be greatly reduced. An outside air supply must be provided to the burners whenever the presence of these compounds is suspected. Warranty will be invalid if the heater is exposed to halogenated hydrocarbons.

2.3 National Standards and Applicable Codes

All appliances must be installed in accordance with the latest revision of the applicable standards and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in Public Garages, Aircraft Hangars, etc. may be applicable.

WARNING

Fire Hazard

Keep all flammable objects, liquids and vapors the minimum required clearances to combustibles away from heater.

Some objects will catch fire or explode when placed close to heater.

Failure to follow these instructions can result in death, injury or property damage.

SECTION 3: CLEARANCES TO COMBUSTIBLES

3.1 Required Clearances to Combustibles

Clearances are the required distances that combusti- ble objects must be away from the heater to prevent serious fire hazards. Combustibles are materials that may catch on fire and include common items such as

wood, paper, rubber, fabric, etc. Maintain clear- ances to combustibles at all times for safety.

Clearances for all heater models are located on the burner of the heater and on Page 4, Figure 3 through Page 7, Figure 12 in this manual. Check the clear- ances on each burner for the model heater being installed to make sure the product is suitable for your application and the clearances are maintained. Read and follow the safety guidelines below:

• Keep gasoline or other combustible materials including flammable objects, liquids, dust or vapors away from this heater or any other appliance.

• The stated clearances to combustibles represents a surface temperature of 90° F (32°C) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, triply, etc) may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent materials are protected from degradation.

• Maintain clearances from heat sensitive equipment and workstations.

• Maintain clearances from vehicles parked below the heater.

• Maintain clearances from swinging and overhead doors, overhead cranes, vehicle lifts, partitions, storage racks, hoists, building construction, etc.

NOTE: 1. All dimensions are from the surfaces of all tubes, couplings and elbows.

2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream from where the burner and burner tube connect.

• In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to the combustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a thermostat, signs must be posted in a conspicu ous location.

• Consult local Fire Marshal, Fire Insurance Carrier or other authorities for approval of proposed instal- lation when there is a possibility of exposure to combustible airborne materials or vapors.

• Hang heater in accordance to the minimum suspension requirements

• If the radiant tubes must pass through the building structure, be sure that adequate sleeving and fire stop is installed to prevent scorching and/or fire hazard.

2. The overlap at the first and second reflector is a slip overlap.

Thereafter, every third reflector joint is a slip overlap. A slip overlap is achieved by either: a.) both reflectors lay inside a hanger.

(No reflector support needed.)

b.) using a reflector support with

loose screws at the reflector overlap.

3. The remaining reflector overlaps require a non-slip overlap connection. To affix the reflectors together in a non-slip overlap either: a.) use reflector support and tight screws. b.) if both reflectors lay inside a hanger, u-clips or

sheet metal screws may be used.

This section of three reflectors joined together must be affixed to the tube with at least one reflector support with tight screws.

SECTION 6: HEATER I NSTALLATION

The pictorial drawings of the heater construction in Section 6 are schematic only and provide a general guideline of where hangers, reflector supports and U-clips are to be installed.

To ensure proper expansion and contraction move- ment of the reflectors, a combination of U-clips and reflector supports are used. The positioning of reflec-

tor supports and U-clips depends on the individual installation. Use either pop rivets or sheet metal screws instead of u-clips when installing end caps and joint pieces in areas where impact and high wind may be a factor. The following rules must be observed.

FIGURE 22: Tube Termination

8.6 Length Requirements

The maximum vent length allowed is 45' (13.7 m). The maximum outside air supply duct length allowed is 45' (13.7 m).

The total vent length, plus outside air duct length, plus any extensions to minimum heat exchanger lengths, cannot exceed 65' (19.8 m).

Vent length should be limited to less than 20' (6 m). If using vent lengths greater than 20' (6 m), condensation will form in the vent pipe. Insulation and additional sealing measures (high temperature silicone at all seams) are required. Optional heat exchanger beyond minimum lengths is considered as vent length for length determination.

Subtract 15' (4.6 m) of maximum allowed vent or duct length per vent elbow if more than two are used.

Gas can leak if piping is not installed properly.

Do not high pressure test gas piping with equipment connected.

Failure to follow these instructions can result in death, injury or property damage.

SECTION 9: GAS PIPING

There is an expansion of the tube with each firing cycle. This will cause the burner to move with respect to the gas line. This can cause a gas leak resulting in an unsafe condition if the gas connection is not made in strict accordance with Figure 23.

Meter and service must be large enough to handle all the burners being installed plus any other connected load. The gas line which feeds the system must be large enough to supply the required gas with a maxi- mum pressure drop of 1/2" wc When gas piping is not included in the layout drawing, the local gas supplier will us

Gas lines must meet applicable codes: United States: The Flexible Stainless Steel Gas Hose (US models) supplied with the heater is certi- fied per the Standard for Connectors for Gas Appliances, ANSI Z21.24/CSA 6.10 - latest revision.

II control will flash in various patterns to indicate status. The LED status indication chart provided below gives a summary of possible faults.

LED Status Indicates

Off No power to the control

Bright-Dim Normal Operation.This indication

shows whenever the system is pow- ered, unless some abnormal event has occurred.

2 Flashes Pressure switch remains closed

longer than 30 seconds after a call for heat begins (pressure switch stuck closed). The SmartValve

II checks the status of the pressure switch con- tacts and must see a change in the contact with every firing cycle. Placing a jumper at the switch out of sequence will result in a fault, with the LED indicator flashing 2 times.
