• For proper draft hood attachment, the draft hood legs may be angled slightly inward. • Place the draft hood legs in the receiving holes on the top of the water heater. The legs will snap in the holes to give a tight fit. Secure the legs of the draft hood with the supplied draft hood brackets. • Place the vent pipe over the draft hood. With the vent pipe in position, drill a small hole through both the vent pipe and draft hood. -

Page 25: Operational Conditions
Operational Conditions (Continued) Read this manual first. Then before checking the water heater make sure the gas supply has been turned “OFF”, and never turn the gas “ON” before the tank is completely full of water. Leakage Checkpoints Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater, see Figure 27. A. Water at the draft hood is water vapor which has condensed out of the combustion products. This is caused by a problem in the vent. -
