Installation Instructions
PLEASE FOLLOW LOCAL CODES ABOUT CONDENSATE PIPING.
• This water heater is a high efficiency, fully condensing appliance which produces condensate during
operation. Therefore, it is necessary to install condensate piping. The water heater incorporates a col-
lection, neutralization, and removal system which must be properly drained in order to ensure proper
operation of this appliance.
• The water heater is supplied with a pre-installed condensate neutralization system. No additional neu-
tralizer is required unless local code dictates otherwise.
• In order to drain the condensate, a 15mm (1/2" BSP) male thread fitting is provided at the base of the
water heater.
DO NOT FIT ANY VALVES OR REDUCE THE SIZE OF THIS FITTING OR THE CONDENSATE PIPING
TO LESS THAN 15mm (1/2" BSP).
• Use plastic pipe, such as PVC, for the drain line. Do not use steel, black iron, or any other material which
can corrode when placed into contact with water.
• Keep the length of the drain pipe as short as possible.
• Horizontal runs must be sloped 1/50 downwards the drain.
• The end of the drain pipe must not be submerged in water or blocked in any way.
• Be sure to check that condensate is freely flowing from the drain piping after the system has been
installed. Condensate will begin flowing out of the water heater within 15 minutes after operation has
started.
• Take measures to prevent the condensate drain lines from freezing (insulation, heat tape, electric heat-
ers, etc.).
