the traditional Approach
• Higher operating costs
• Large fluctuations in room temperature
• Slow response to thermostatically controlled heat settings
• Poor distribution of the heat provided through leaky ducts
the Rinnai Approach
• Energy-efficient and economical zone or whole-house heating
• Wall furnace quickly adapts to small temperature changes
• Modulating blower and gas valve automatically adjust to individual heating needs,
providing comfortable, consistent temperature from ceiling to floor
• No ductwork required

temperature-Sensing thermistor
• Consistently monitors room temperature 2” off the floor
• Accurately detects temperature changes less than one degree
Rinnai Response
• Within 10 seconds, the Rinnai wall furnace begins to gently heat the room at low fan speed
• It increases fan speed and BTU output if necessary to achieve the desired temperature
• Once the desired temperature is achieved, the furnace goes into standby mode
Room Monitoring
• As the temperature of the room gradually drops, the wall furnace restarts and gradually warms
the room back to the desired temperature
• If there is a sudden injection of cold air, the furnace automatically adjusts fan speed and BTUs to
quickly restore the set temperature

Rinnai venting uses outside air
which improves indoor air quality.
It is easy to install and can be
vented up to 13 feet.
Modulation technology
Modulating technology
replaces only the heat escaping
the structure by continuously
operating at heating levels
based on the current demand,
which leads to lower gas usage
and higher levels of comfort.
Newly designed, user friendly
With the new user-friendly control panel,
you can choose a set temperature or
program the timers to take total control
over your heating needs.
