QVM 9

Series

8

1.  Continuous Hot Water

    Its On Demand! The QVM 9 makes running-out-of-hot-water obsolete. 

2. Everything Built-in

    Installs in half the time.   

3. Baked-on Beauty

    The high quality ceramic finish is baked on and keeps the exterior looking new and lustrous 

for years to come. 

4. Room Thermostat FR-5

    Convenient and accurate, the large digital display is easier to read, easier to use. Our 

new room thermostat gives the consumer digital control over several heating functions. 

5. System Timer  

Save energy during times the home is unoccupied. Just set and activate the timer and leave. 

The unit turns off for pre-programmed intervals until you return. 

6. Performance Indicator

    With  the  use  of  the  FR-5  electronic  room  thermostat,  the  (LED)  will  conveniently 

display the current operating condition of the unit such as, room temperature, normal operation, etc. 

7. Continuous-Discharge Ignition(C.D.I.)

  Direct ignition design does not require a pilot burner saving gas and money. 

8. Combustion Safety Protection

    If the unit fails to ignite after the “HEAT ON” button is pressed, or if the flame 

is extinguished due to a gas shortage, the 

flame detector will shut down the unit. 

9.  Always Balanced Operation

    Despite fluctuating wind conditions, changes in atmospheric pressure and other 

external disturbances, the variable-speed combustion blower provides optimum performance. 

10. Exhaust Safety Protection

    While  operating,  the  exhaust-discharge  fan  is  continuously  monitored.  The  unit 

will be immediately stopped to prevent fumes from entering the home, if the wind gusts become excessive or 
if the flue exhaust has become blocked. 

11. Smart  Re-Start

    Should  the  unit’s  flame  fail  due  to  strong  winds  or  low  gas  pressure,  the  unit  will 

automatically restart. In cold weather climates, manual resets could cause freeze damage. 

12.  Safety Protection During Power Outages

    When the power fails, the gas valve is automatically shut down. 

13. Automatic Fill & Refill

    If for any reason the water level in the system drops to an unsafe level, the unit will 

automatically open the fill valve. 

14. Automatic Air Bleed

    Each unit has 2 built-in air bleed devices. One is manual and used for quick fill and 

venting convenience; the other is air-activated and operates automatically. 

15. Removal of Impurities

    Each  unit  comes  equipped  with  a  built-in,  cleanable,  heavy  duty,  particulate water 

filter for trapping impurities and preventing the pipes from clogging. This is a maintenance item. 

16. Air-Ratio Controller

    The  air  ratio  is  monitored,  adjusted  and  controlled  prior  to  and  during  each  operating 

cycle  and  will  automatically  adjust  the  combustion  rate.  The  air-ratio  controller  prevents  unsafe  operating 
conditions and also senses excessive gusts of wind in the flue system. 

17.  Proportional Temperature Control

    This control is designed to continually analyze water flow and usage while 

maintaining the outgoing water at a constant, even temperature. 

18. Condensing (QVM 9) Models

    These  fully  condensing  units  are  engineered  to  recover  and  convert  the 

normally wasted heat from the discharge flue gasses to supply additional hot water. 

19.  New BTU Booster Flue Kit 

(standard equipment with QVM8 and QXM8, optional QVM9)    This pre-engineered 

venting  system  adds  an  additional  2%  to  the  unit’s  combustion  efficiency  by  pre-heating  the  incoming 
combustion air before it enters the unit. A single, 4-

1/4

″

  diameter penetration through an exterior wall is all 

that  is  required  for  this  concentric  venting  system.  Built  of  durable,  polished,  stainless  steel.  Kit  includes 
clamps, connectors, gaskets, pipe and trim ring.
