installation instructions
Step 3 – Connecting
Plumbing
• For exposed plumbing connection, connect the cold water inlet pipe from the
base of the Hydroboil 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 Hydroboil.
• The Hydroboil 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 5).
Venting
The Hydroboil 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 Hydroboil 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 Hydroboil 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).
• For concealed vent plumbing, direct the vent outlet from the rear of the
Hydroboil.
• Alternatively install a visible tundish. (see adjacent diagram) and plumb to
trapped waste.
