Step 3 – Connecting

Plumbing

For exposed plumbing connection, connect the cold water inlet pipe from the base
of the Econoboil directly to the ½” BSP compression fittings with nuts and olives
supplied.

For concealed plumbing connections, connect the cold water pipe through the rear
of the chassis using a ½” BSP capillary elbow.

Cold water pipes must be flushed before connection to the inlet. Any clogging due
to sediment or fines will adversely affect the operation of the Econoboil.

The Econoboil must be installed with an isolating valve which allows it to be
isolated from the mains water supply for servicing.

Water pressure requirements. (See Technical specification , page 6).

Venting

The Econoboil is an open vented water heater, and as such it is
essential to provide an air gap in the venting arrangements, as shown
in the adjacent diagram.

A vent at the base of the Econoboil must be plumbed to a safe location as,
under certain conditions, it may discharge cold, boiling water and/or steam.

For concealed or exposed vent plumbing, connect vent outlet from the base of
Econoboil to a Ø15 mm pipe which has a continuous fall, is no more than 3m
long, has no more than 3 right angle bends, and discharges to a waste water
drain. (the vent outlet must be visible).

resistance meter of minimum accuracy of 5% full scale deflection.

• Isolate power supply.

• Verify meter ohms range, connect leads together, reading
should be 0 ohms.

• Connect one test lead to the earth
of the power lead.

• Connect the other test lead to a
cover fixing screw, then the tap.

Warning ! The water may

be boiling

• Verify that in every
instance the electrical resistance
does not exceed 1 ohm.

Turn water supply ON. Water will flow into the Econoboil, check connections for leaks. Wait approximately 5
minutes then pull the tap forward to test for water flow.

Turn the mains electrical power ON only after the water flows freely from this outlet. After a short period, boiling

Operation

Boiling water

Zip Econoboil is fitted with a two-way tap for instant boiling water.
For instant boiling water, gently pull the top of the tap forward.
Boiling water will flow until the tap handle is released.
This operation gives fingertip flow control for safe filling of cups and mugs.
To fill larger vessels such as teapots and saucepans, rotate the tap 180º and depress it until it locks into a horizontal

position. Boiling water will flow until the tap is returned to its normal vertical position.
This operation allows the vessel to be filled without holding your hand where it may be affected by steam.
