3.3 Unpacking the heater
Before installing the unit, be certain you have the correct heater for
your type of Gas - Propane or Natural Gas. Identification labels are
found on the shipping box, and on the rating plate which is located on the
right side panel of the cover.

3.3.1 The box includes
• Tankless water heater
• Bracket for wall hanging the heater
• Installation manual
• Energy Guide label (in the front cover)
The RTG 199ME is not approved or designed for:
• Manufactured (mobile) homes, boats or any mobile installation.
(Modular homes are acceptable for installation).
• Use above 8000 ft A.S.L. altitude (see page 22).
• Outdoor installation without installation of Outdoor kit (BTOK).
• Applications where inlet water temperature is higher than 140°F
(60°C). A 3-way valve or mixing valve must be installed before
the appliance if inlet water temperature exceeds this limit.
3.3.2 Remove front cover
▶ Loosen the two Phillips head screws located on bottom rear of cover.

1) To measure Gas Pressure, see Measuring Gas Pressure, chapter 4.14, page 32.
2) Activation varies with inlet water temperatures from 0.5 - 1.6 gallon/minute (1.9
- 6.1 l/m).
3) Protection against water drops.
If appliance is installed at elevations above 2000ft, refer
to chapter 4.3.8 Fan speed adjustment.
