Roof Damage Warning and Disclaimer
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air” devices should be provided for all powered air handling systems. The manufacturer does not reco mmend the use of downward flow systems (suction). Severe roof damage can result from any block age of air passages. Running fans during high humidity/cold weather conditions can cause air exhaust or intake ports to freeze.

4. Installation

Do not use propane tanks which have previously been used for ammonia unless they have been purged according to procedures of the national LP association.
Investigate to be sure that the fuel supply system complies with all local codes for LP gas installations.
WARNING
Always disconnect and lock out power before working on or around heater.
Fuel Connection
WARNING
Liquid Propane Models
1. LP models are designed to run on liquid propane, with liquid draw from the propane tank. Avoid using propane supply tanks that have been use for vapor draw for long periods of time. When using liquid draw systems any moisture that may be present in tank or lines may freeze when system is used in cold weather. To avoid this, the usual precaution is to purge the system with methanol.
2. Run proper size line (See Specifications on Page 9) to pipe train on heater. Have a qualified gas service person inspect installation to be sure everything is installed according to local codes and ordinances.
3. After installation is complete check all connections for leaks. Use liquid detergent or comparable substance. Wear rubber gloves and eye protection. Avoid contact with liquid propane. DO NOT USE FLAME FOR LEAK TESTING.
Propane Vapor Models
1. Propane vapor models are designed to run directly off of supply tank or from a separate external vaporizer.
2. Run proper size line (See Specifications on Page 9) to pipe train on heater. Have a qualified gas service person inspect installation to be sure everything is installed according to local codes and ordinances.
3. After installation is complete check all connections for leaks.
Natural Gas Models
1. Natural gas models are similar to vapor models, but have a larger orifice to accommodate lower pressure, sometimes found with natural gas.
2. Run proper size line (See Specifications on Page 9) to pipe train on heater. Have a qualified gas service person inspect installation to be sure everything is installed according to local codes and ordinances.
3. After installation is complete check all connections for leaks.
Standard Heater Electrical Installation
Standard electrical safety practices and codes should be used when working with a heater. Refer to the National Electric Code Standard Handbook by the National Fire Protection Association. A qualified
electrician should make all wiring installations.
IMPORTANT: Heater must be interlocked with fan for safe operation.
Heater Power Connection
1. Connect power cord to fan control box.
2. Make field connections in fan box as shown in Figure 4A.
3. Connect deluxe thermostat control as shown in Figure 4A.
IMPORTANT: Thermostat must be installed for safe operation.
