- You MUST install this water heater according to all directions and specifications
contained in this manual. Failure to properly install the heater can result in property
damage or severe injury or death by burning, explosion, or asphyxiation due to
carbon monoxide.

- You MUST check the exhaust flue for obstructions at the initial installation and at
least annually thereafter.

- You MUST check all connections for gas leaks with soapy water before firing the
unit. This must be done at the initial install and after every propane bottle change if
using an LP model. If you detect a gas leak of any kind, DO NOT fire up your unit.

- You MUST check for gas leaks by smell. Understand that LP is heavier than air
and may sink to ground level. If you detect a gas leak of any kind, DO NOT fire up
your unit.

- You MUST observe the unit in operation for several cycles before leaving it
unattended.

- Unit MUST be hung vertically, with the water and gas connections at the bottom
and the exhaust at the top.

- You MUST use a carbon monoxide detector in conjunction with this, or any, gas
burning appliance.

- Do NOT expose the water heater to strong wind (including that from fans) or rain.

- Do NOT install the water heater near flammable or volatile substances. Do not
handle or store these substances near the heater (gasoline, acetone, motor oil,
paint thinners or any other flammable or volatile substance).

- Do NOT use tubing or piping that is aging or cracked in any way.

- Do NOT use this appliance with any type of gas other than that indicated on the
data plate located on the side of the unit. Death or severe injury may result.

- Do NOT attempt to modify the internal components of this appliance.

- Do NOT install the water heater in a sealed room or in a room with poor air
circulation.

- You MUST install the exhaust pipe to properly discharge the exhaust gases.

- Do NOT block the exhaust pipe or the air inlet at any time. This can cause
incomplete combustion and can lead to gas poisoning.

- When the water heater is in use, do NOT touch the body of the heater. Touch the
knobs only, as the body of the heater can become very hot to the the touch.

- Prevent scalds! While using the water heater, always check the water
temperature and adjust as needed before use.

1. Water - controlled automatic ignition:

When water flow is detected, heating is provided immediately with a double­ignition device. The flame is sensed by ions. This sensitive control makes the unit
easy and convenient to operate.

2. Auto - cut off protection:

The auto-cut-off protection will shut off the gas supply immediately if the flame goes
out for any reason.

3. Energy savings:

The advanced combustion system comes with a Winter/Summer switch. In winter,
when incoming water temperatures are lower, the winter setting increases the size
of the flame to compensate with extra heating. In summer, when incoming water
temperatures are lower, the summer setting reduces the flame.This provides more
comfort and energy savings in the form of lower gas consumption in warmer
months.

4. Low water pressure start up function:

This unit requires only 8 PSI to fire, making it suitable for users with low water
pressure, or those who are using it to supply hot water to upper floors. Please note
that the water flow and water pressure are not the same. Sufficient flow is always
required to keep the overheat safety sensor from shutting the unit off.

5. Anti - freezing protection:

When the temperature is below freezing, remove the water discharge valve to
discharge accumulated standing water inside the internal pipes. This will keep the
unit from freezing.
