Although these heaters may be used in many applications other than space heating (e.g., process heating), Space-Ray will not recognize the warranty for any use other than space heating.

This heater is for Indoor or Outdoor Installation and can be used in either Vented or Unvented mode. The term Unvented actually means Indirect Vented. While the products of combustion are expelled into the building, national codes require ventilation in the building to dilute these products of combustion. This ventilation may be provided by gravity or mechanical means.

This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point materials exists, it could result in property damage or death. This heater must not be installed in a spray booth where the heater can operate during the spraying process. Consult your local fire marshal or insurance company.

High Altitude:

Appliances are supplied as standard for altitudes of O to 2,000 feet (0-610 m). High-altitude ratings are obtained by a change in the orifice size. When ordered for high altitude installations, burners are supplied by the factory ready for high altitude installation. Check the nameplate for altitude before proceeding with the installation. In Canada the adjustment for altitude is made in accordance with Standard CGA 2.17, Gas-Fired Appliances for Use at High Altitudes.

9.0) TYPICAL SUSPENSION METHODS

SUSPENSION HAZARD

All materials used to suspend the heater must have a minimum working load of 115 lbs. All “S” Hooks must be crimped closed.

If a “Trapeze” method of hanging is used, the chain and turnbuckle used to suspend the heater must have a minimum working load of 230 lbs. “S” hooks must have a minimum working load of 120 lbs.

Never use the heater to support a ladder or other access equipment. Failure to do so may result in death, serious injury or property damage.

Various means of suspending the heater can be used. The following should be observed:

1.Use only noncombustible materials for suspending hangers and brackets.

2.Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent structure with adequate load capacity.

3.Heaters subject to vibration must be provided with vibration isolating hangers.

4.A minimum No. 2 chain with a working load limit of 115 lbs. is required when using four (4) separate chains. If a “trapeze” method of hanging is desired, you must use a chain with a load limit of at least 230 lbs, a turnbuckle (if necessary) with a load limit of at least 230 lbs, and “S” hooks with a load limit of at least 115 lbs. Typically, 2/0 chain and 3/8” eye & eye turnbuckle have a minimum working load of 230 lbs; #80 “S” hooks have a minimum working load of 115 lbs.

5.Turnbuckles can be used with chains to allow leveling of the heater. All “S” hooks and eye bolts must be manually crimped closed by the installer.

6.When using rigid means for heater suspension (rod, flat bar, etc.) provide sufficient lengths or swing joints to compensate for expansion. See Figures b and c.

7.The heater can be mounted horizontally or at angles of 30º, 60º, or 90º indoors. The maximum mounting angle is 45º when installed outdoors. The long axis of the heater should be level whether it is mounted horizontally or angled.

8.If the heater is to be mounted horizontally or at an angle up to 60º, use the hanging brackets installed on the heater. See Figure 1 on Page 9.

9.If the heater is to be mounted at a 90º angle, remove the existing hanging brackets from each end of the heater and replace with “L” shaped brackets. See Figure 2 on Page 9. (Note: “L” shaped brackets are supplied as an accessory item. Order Kit No. 42929000.)

10.IMPORTANT: When the heater is angle mounted, the exhaust side should be up.

If a “trapeze” method is used for tube support/hanger brackets (shown below), the minimum chain length for the two connecting chains is 36” to minimize any vibration that might be generated by the draft inducer assembly. If these chains must be less than 36”, then do not use the trapeze method and, instead, use individual chains on each tube support/hanger bracket.

10.0) HEATER ASSEMBLY

CUT HAZARD

Sheet metal parts, particularly reflectors and vent have sharp edges. Always use gloves when handling.

Failure to do so may result in death, serious injury or property damage.

The heater is completely factory assembled. The gas manifold tubing requires field assembly; the recommended procedure is as follows:

1.Add the manifold tube and fittings. The required components are packaged inside the control box.

a.Remove the access panel. Apply pipe joint compound to the 5/8” tube x 1/2” Male NPT compression union and screw it into the valve. The pipe joint compound should be resistant to the action of liquefied petroleum gases.

b.Assemble the 5/8” tube x 1/2” Female NPT compression union to the opposite end of the manifold tube, then slide the manifold tube through the hole on control box.

c.Connect the manifold tube to the valve at the compression fitting. When connecting, use a wrench to hold the compression union on the valve.

d.Leak check the gas line up to the gas valve using soap solution method at a pressure of 14” w.c. Replace the access panel.

Note: Components packaged in control box.

4.If the heater is to be used Indoors and Vented to the outside, install the flue collar supplied with the heater by placing the collar directly over the gasket. Secure the collar flange with clamps. See Figure 4 on next page.

5.Attach a 6” diameter flue pipe to the flue collar. Place an approved vent cap to the outside end of the flue pipe. See Section 14.0) for flue vent requirements.

6.If the heater is to be used Indoors and Unvented, order the Indoor Unvented Kit (Part #42406000). Remove the clamps and install the Exhaust Hood directly over the gasket. See Figure 5 on next page.

7.If the heater is to be used Outdoors, order the Outdoor Kit (Part #42411000). Install the Exhaust Hood as instructed above in #4. Remove the solid cover panel from the side and install the Inlet Air Hood. Remove the perforated cover panel from the top and replace it with the solid cover panel. See Figure 5 on next page. After completing the assembly, silicone sealant should be utilized to seal the access panel openings. If the installation site is subject to excessive wind conditions, it might be necessary to utilize pop rivets to secure the reflectors to the heater body.
