Step 6 Fitting the Drain Pipe
(see Fig. 14)
When the Water Heater is in place on the floor, mark a location for where the pressure relief / drain valve discharge
pipe will come through the floor. Carefully remove the Water Heater and drill a hole in the floor, minimum diameter
20mm, ensuring that there are no obstructions on the underside of the vehicle i.e. gas pipes, chassis members etc.
Refit the Water Heater, inserting the discharge pipe in the hole and ensure that it is left open to the atmosphere at all
times.

Step 7 Secure Water Heater to Floor
To secure the Water Heater to the floor, use 4 screws (No. 8 x 1 ¼”) provided (see Fig. 15).
