CONNECTIONS – PLUMBING
32
LEFT AND RIGHT HAND SIDE WATER CONNECTIONS
A kit is supplied with an E6X series water heater to plug or cap off the unused cold water and hot water fittings.
The kit contains:
2 x ¾” brass plugs
2 x plastic caps
2 x insulation rubber discs, pre-fitted into plastic caps
Plugging or Capping Off Unused Connections
•
Apply approved sealing tape or compound to the thread of
each plug.
•
Fit the
¾” plugs to the unused cold water fitting and unused
hot water fitting. Tighten the plugs
using a 3/8” square
driver.
•
Fit a plastic cap with its insulation rubber disc over each
plug.
TEMPERATURE PRESSURE RELIEF VALVE
The temperature pressure relief valve is shipped in a plastic bag attached to the water heater. The temperature
pressure relief valve must be fitted before the water heater is operated. Before fitting the relief valve, make
sure the probe has not been bent.
To fit the relief valve:
•
Seal the thread with an approved thread sealant such as Teflon tape - never hemp. Make sure tape does
not hang over the end of the thread.
•
Hand tighten
the valve into the opening marked “Relief Valve” (refer to the
page 28).
•
Using a spanner engaged on the valve’s spanner flats and applying medium pressure to tighten, turn the
relief valve an additional ½ to 1 ½ turns to secure and make the joint water tight, leaving the valve drain
pointing downwards.
Warning:
Do not use a pipe wrench or poor fitting tool on the valve body nor over tighten the valve,
as this could damage the valve and prevent safe operation.
•
Operate the easing lever on the valve to check the smooth operation of the valve plunger. It is very
important the lever is raised and lowered gently. The lever should move smoothly and without undue force.
•
If the lever cannot be moved or is jerky in its movement, then the valve has been damaged and must be
replaced.
•
A copper drain line must be fitted to the temperature pressure relief valve (refer to
page 33).
•
The valve must be insulated with closed cell polymer insulation or similar (minimum thickness 9 mm) and
the insulation installed so as not to impede the operation of the valve.
The insulation must be weatherproof and UV resistant if exposed.
