Copper Brute B4 Volume Water Heaters
Vent pipes, drafthoods, and heater tops get
hot! These surfaces can cause serious burns.
Do not touch these surfaces while the heater
is in operation. Adding a vent cap reduces the
temperature on the top.
For your safety, when starting the heater, keep your
head and face well away from the lower firebox
opening to prevent any risk of personal injury.
LP GAS: To avoid possible injury, fire and
explosion, read and follow these precautions and
all instructions on this heater before lighting. This
heater uses LP gas which is heavier than air and
will remain at ground level if there is a leak. Before
lighting, sniff at ground level.
If you smell gas, follow these rules:
1. DO NOT light matches. DO NOT turn electric
lights or switches on or off in area. DO NOT use
an electric fan to remove the gas from area.
2. Shut off gas at LP tank.
3. Telephone gas company and fire department
for instructions. Give your name, address and
phone number.
If your LP tank runs out of fuel, turn off gas at the
heater. After the tank is refilled, the heater must be
relit in accordance with the instructions found on the
inside of the heater. DO NOT attempt repairs on the
gas control or heater. Tampering is dangerous and
voids all warranties.
3.2 Start-Up Procedure
Lighting instructions can be found on the inside
of the heater. To start up the heater:
1.
Make sure the system pump is running and there
is water flow.
2.
Remove the control access panel.
3.
Set the temperature control (see Figure 30) to its
lowest setting.
4.
Turn electric power to the appliance to off.
5.
Turn manual gas valve off.
6.
Wait 5 minutes to clear out any gas, then smell
for gas, including near the floor. Be sure to smell
next to the floor because some types of gas are
heavier than air and will settle on the floor.
This heater is equipped with an ignition device
which automatically lights the burner. Do not try to
light the burner by hand.
