Install and Assemble the Heater

Back

NOTE: For best operation, keep the heater level.

  1. To prepare the H-45 Type II (Liquid Fuel) Heater for operation (after you have burned off the protective film), place the heater on the ground under a tent stack shield opening. If used on top of a tent floor, the heater must be set on a bed of sand or placed on three or four bricks. Level the base by eye. NWTC uses a sawed off 55 gallon drum with dry sweep as a base.
  2. Open the front base heater door (1), pull the priming cup (2) on the retainer wire (3) out of the heater body base until the wire fully extends, and set aside.
  3. Remove the top heater shell (4) from the heater body base (8) by loosening the wing nuts on the bolt and wing nut assemblies (21) and sliding them out of the brackets (22) on the top heater shell (4). Set the top heater shell (4) aside. If not already done, remove all the components stored inside the heater.
  4. Replace the burner shell assembly (5) in the heater body base (8). If necessary, rotate the burner shell assembly (5) to ensure that the pipe nipple (6) aligns with the left side of the front base heater door opening (7) in the heater body base (8). Pull the flow control burner hose (9) through the front base heater door opening (7). The burner shell assembly (5) and adapter ring (10) welded to its top must be level and fully engaged all around the circumference of the heater body base (8).
  5. The super heater (11), burner cap assembly (12), and high fire ring (13) are installed when shipped. Ensure that these parts are in place as illustrated.
  6. Insert the fuel flow control valve (14) into the bracket holder (15) on the heater body base (8).
  7. Attach the free end of the flow control burner hose (9) to the flow control outlet (16) on the bottom of the fuel flow control valve (14). To do this, pull back on the female Quick Disconnect (QD) fitting on the end of the flow control burner hose (9), insert it on the flow control outlet male QD fitting, and release the female QD fitting. Gently pull on the flow control burner hose to ensure the connection is secure.
  8. Attach the female QD fitting on the fuel overflow hose (17) to the fuel overflow male QD fitting on the fuel flow control valve (14). To do this, pull back on the female QD fitting on the fuel overflow hose (17), insert it on the fuel overflow male QD fitting (18) on the fuel flow control valve (14), and release the female QD fitting. Gently pull on the fuel overflow hose to ensure the connection is secure. Set the free end of the fuel overflow hose aside.
  9. Connect the female QD fitting (19) on the fuel supply hose (23) to the fuel supply male QD fitting (20) on the fuel flow control valve (14). To do this, pull back on the female QD fitting (19) on the end of the fuel supply hose (23), insert it on the fuel inlet male QD fitting (20), and release the female QD fitting (19).
  10. Place the top heater shell (4) on the heater body base (8). Place the bolt and wing nut assemblies (21) in the brackets (22) on the top heater shell (4) and tighten the wing nut.
