SECTION 4: BEFORE USING THE HEATER

4.4 Venting Requirements

The CGTH-Series heater must be installed with the venting system supplied or with the optional venting kit available from Roberts-Gordon. DO NOT connect this heater to a separate chimney, and do not com- mon vent with any other fuel burning appliance.

The CGTH-Series heater employs a balanced flue/air venting duct system and must conform to the follow- ing length requirements:

Maximum Length: 10' (3 m)

Minimum Length: 2' - 6" (.76 m)

Maximum Elbows:Two with natural gas units, one with propane gas units

4.4.1 Venting Codes

WARNING

Carbon Monoxide Hazard

Heater must be exhausted outside. Use materials supplied.

This heater needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air.

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

The location, size, installation and termination of vents, as well as the required safe distances from combustibles when penetrating combustible walls, must comply with local codes and recommendations of the local gas company. United States: Refer to National Fuel Gas Code, ANSI Z223.1 - latest revi- sion (same as NFPA 54). Canada: Refer to CSA B149.1 Natural Gas ans Propane Installation Code.

4.4.2 Balanced Flue Construction

The balanced flue consists of a 3" (8 cm) diameter flue which is concentrically positioned inside a 5" (12.5 cm) diameter vent pipe (See Figure 2). The 5" (12.5 cm) diameter vent supplies outside air for com- bustion while the 3" (8 cm) diameter flue carries the products of combustion from the heater.

The balanced flue is applicable for both horizontal and vertical venting arrangements. Vertical venting will require the optional roof venting kit available from Roberts-Gordon.

4.5Non-Residential Installations 4.5.1 Aircraft Hangars

The CGTH-Series heater may be used in certain areas of aircraft hangars. Installation in aircraft hangars must be in accordance with the following codes: United States: Refer to Standard for Aircraft Hangars, ANSI/ NFPA-409 - latest revision. Canada: Refer to Standard CSA B149.1 Natural Gas ans Propane Installation Code.

•Heaters in aircraft storage or service areas must be installed a minimum of 10' (3 m) above the upper surface of wings or engine enclosures of the highest aircraft which may be housed in the hangar. (This should be measured from the bottom of the heater to the top of the wing, or engine enclosure, which- ever is highest from the floor).

•In other sections of aircraft hangars, such as shops or offices, heaters must be installed a minimum of 8' (2.4 m) above the floor.

•Heaters installed in aircraft hangars shall be located so as not to be subject to damage by aircraft, cranes, movable scaffolding or other objects.

•When installed over hoists, the required safe dis- tances from combustibles must be maintained from the uppermost point of the combustible materials placed on the hoist.

4.5.2 Public Garages

The CGTH-Series heater may be used in public garages. Installation in public garages must be in accor- dance with the following codes: United States: Standard for Parking Structures NFPA-88A - latest revision or the Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA-30A - latest revision. Canada: Refer to CSA B149.1 Natural Gas ans Propane Installation Code.

•Heaters must be installed a minimum of 8' (2.4 m) above the floor. Required safe distances to combus-
