INSTALLATION

Pre-Installation Checklist

 

‰

Check for any damage that may have been incurred during shipment .

 

‰

If damage is found, document the damage with the transporting agency and immediately contact your distributor . 

If you are an authorized Distributor, follow the FOB freight policy procedures .

 

‰

Ensure that gas specifications and electrical characteristics of the unit are compatible with the gas and electric 

supplies at the installation site .

 

‰

Read this booklet and become familiar with the installation requirements of the unit .

 

‰

If you do not have knowledge of local requirements, check with the local gas company or any other local agencies 

who might have requirements concerning this installation .

 

‰

Before beginning, make preparations for necessary supplies, tools, and manpower .

 

‰

Before installing the unit, check the supporting structure to ensure that it has sufficient load-carrying capacity in 

accordance with 

Weights

 section .

 

‰

Mounting angle must be within the tolerance allowed .

Suspension Mounting

⚠ DANGER ⚠

The installer is responsible for suspension of the heater. Under no circumstances should either the 

gas supply line or electrical supply line to the unit be used to provide assistance in suspension. 

Do not run any gas or electric service lines above or below the heater or near the path of the flue 

products.

⚠ CAUTION ⚠

 

• If a heater is located in an aircraft hangar or near overhead doors, it should be rigidly mounted 

to prevent swinging.

 

• DO NOT ANGLE HEATERS MORE THAN 30 DEGREES OR LESS THAN 5 DEGREES. For proper 

operation, the heater must be level, whether angle-mounted at 5 or 30 degrees. The heater is NOT 

design-certified for use above 30 degrees (and voids the manufacturer’s warranty as well). A 

horizontal or zero-degree angle is not recommended because flue gases coming off the burner 

surface could potentially create an overheating condition for the gas controls. At a 5-degree 

angle, a natural upflow of flue gases safely exits the heater.

 

• All models must be installed with the gas manifold located on the low end.

 

• Check local codes for mounting requirements and for permission to use flexible gas connectors. 

Local codes may require rigid mounting. It is recommended that either the piping or the mounting 

be flexible to prevent fatigue failure from vibration and/or thermal expansion.

 

Suspend the heater with the gas manifold located on the low end using either 3/8-inch (10-mm) threaded rod for 

rigid mount or chain and S-hooks for chain mount (see 

Figure 3

, DETAIL A) . Chain with a 200-pound (91-kg) 

working load (1/0 Tenso) is recommended . S-hooks must be a minimum 1/4-inch (6 .3-mm) diameter wire and 

must be closed after installation .

 

As an exception, it is permissible to suspend the following single-burner models with the gas valve on the high end: 

RIHL unit size 050 and RIHN unit sizes 030 and 060 (see 

Figure 3

, DETAIL B) . Mount these units with the gas 

manifold (A) angled upward, the gas valve (B) toward the high side, and the mounting angle at 5- to 30-degrees .

 

If permissible by local code, it is recommended that the heater be suspended using chain and S-hooks (see 

Figure 

3

DETAIL C) . Suspend the heater as follows using either the chain and S-hooks provided in option UE1 or UE2 

or field-supplied chain and S-hooks:

a .  Securely connect one end of long chain to overhead building structure using S-hook A . Connect other end of 

long chain to back of heater using S-hook B .
