Danger: Checkup!

Check the fixing brackets and vent pipe

yearly for damage or wear. Replace if

necessary.

Danger: Check the gas!

- Check that the rating plate indicates

the correct type of gas.

- Check that the gas supply line is sized

at 60Hz. May result in fire or electric

shock.

Warning: Use Extreme Caution if Us-

ing With a Solar Pre-Heater!

Using this unit with a solar pre-heater

lutely necessary, use mixing valves to

ensure output temperatures do not get

to scalding levels.

Caution: Do Not Use Equipment for

Purposes Other Than Those Specified!

Do not use for other than increasing the

temperature of the water supply, as un-

expected accidents may occur as a re-

sult.

Caution: Check Water Supply Quality!
