Dayton® Propane

Construction Heater

Ventilation

Follow the mini- mum fresh, outside

air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater.

Provide at least a three-square-foot (2,7m2) opening of fresh, outside air for each 100,000 Btu/Hr rating while running heater.

Installation

Review and understand the

warnings in the General Safety Infor- mation section, pages 2 and 3. They are needed to safely operate this heater. Follow all local codes when using this heater.

Test all gas piping and connections

for leaks after installing or servicing. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
