Page 5: Installation
INSTALLATION The Heat Wagon Model 2730/3050 is a direct fired gas heater intended to be used primarily for the temporary heating of building under construction, alteration, or repair.

Page 6: Proper Set Up
MODEL 2730/3050 (NOTE: The 2730/3050 must be specifically set up for the type of available fuel PRIOR to installa- tion) Model 3050 with built-in vaporizer. The heater will use 44 gallon of L.P. per hour. Use at least one 1000 gal. Liquid withdrawal tank. This will insure 20 hours of continuous operation. - Page 7 Heater can be ducted up to 300 ft of straight 30” for the 3050 and 200 ft of straight 27” for the 2730C duct. For every 90˚ bend cut the total length in half. If the heater is ducted it may be necessary to adjust the air flow switch (located inside control box) by turning adjusting screw CCW until the light on the control box turns on.
