4.2 – INSTALLATION OF THE GAS PIPE
01. Contact your local gas supplier for installation of the gas line to the tankless water heater.
02. Install a shut off valve at the unit.
03. Natural Gas must be at 8” WC, Propane must be at 11” WC.
04. Always check for gas leaks after connecting the gas line to the unit. An electronic gas detector works
best, but soapy water in a spray bottle works as well (bubbles indicate leak).
4.3 – INSTALLATION OF EXHAUST PIPE
The EZ Ultra HE is a forced exhaust tankless water heater which must be vented to the outside using
either the flue provided or 2” solid core PVC/CPVC schedule 40. The flue can be used horizontally
through an exterior wall or vertically through the roof.
01. The flue cannot be connected to any other existing flues or chimneys. It must stand alone either
through an exterior wall or through the roof.
02. Use a metal wall thimble if the flue is to touch any flammable surfaces (wood, insulation, siding).
03. Tape all joints on the flue using aluminum heat tape to prevent exhaust leakage.
5.0 SAFETY PRECAUTIONS
01.
Always check water temperature by hand before entering shower or bath. The temperature may
have been changed. Do not touch the unit cover or the flue outlet while in use.
02.
Do not insert objects into the flue outlet. On colder days steam may discharge from the flue
outlet. This condition is normal for high efficiency appliances.
03.
The vent should be positioned at least 12” away from flammable materials such as trees,
shrubs,
etc.
5.1 HOT WATER RISK
01.
Hot water is dangerous, especially for the young and the elderly or the frail. The EZ Tankless
water heater allows you to precisely control the temperature of your hot water, ensuring safe water
temperature. Water temperature over 125°f can cause severe burns instantly or death from
scalding.
02.
Hot water can cause first degree burns with exposure for as little as:
3 Seconds at 140°f
20 Seconds at 130°f
8 Minutes at 120°f
03.
Test the temperature of the water with your elbow to ensure adequate temperature before placing
a child in the bath or shower.
04.
Do not leave children or an infirm person in the bath unsupervised.
