ARNING

When lit for the first time, the Sterling will emit some 

smoke  and fumes.  This is norm al  “off-gassing”  of 

the  paints an d  oils  used  in  the m anufacturing  and 

assembly  of  the  unit.  Open windows to vent the

room  if nec essary.  The off gassing and fum es  will 

subside after the first 10 to 20 minutes of operation. 

O

DORS AND 

I

MPURITIES

A  heater of this t ype  may  produce  odors d uring 

heater  operation  due to im purities  that  may  exist in 

the  immediate  area.    Sources  of i mpurities  can  be 

cleaning  solvents, paint s olvents,  cigarettes, s moke, 

soot  from  scented  candles, pet hair,  dust,  adhesives, 

new carpet, and/or textiles.  Such odors will dissipate.  

However, opening a wind ow or otherwise providin g 

additional  ventilation  to  the  area can alleviate th e 

condition.  If any odor persists, contact your dealer or 

an authorized service technician.

IGHT

The  Sterling has a batte ry  operated  electric  spark 

igniter,  which  ignites the pilot   light  by m eans  of a 

spark  at the   pilot light  assembly.  To activate the  

igniter, turn the gas control knob to ‘Pilot’ and push 

and  hold  it  down.  You  must  install the included  

battery  for the igniter. The battery   compartment  is 

located  in the lower rear  area  of the s tove.  Do not 

attempt  to light t he  unit  with a m atch  or by any 

means other than the electric spark.

DJUSTMENTS

Once  the Sterling-Ht is set in place, connected and 

assembled as described in the Asse mbly of the Unit, 

Electrical  Connections,  and Gas Suppl

y  & 

Connections sections of this manual, the unit is ready 

to be lit for the first time.  Each unit is  tested prior to 

shipment by the manufacturer, so ignition should take 

place  without  failure.    However,  a  number  of  small 

adjustments  may  be necessary   to com pensate  for 

variations in gas pressure, altitude, and other factors  

particular to each installation. 

Prior  to light ing  the unit  for  the first time, wait 5  

minutes to allow any residual gas within the unit t o 

dissipate.  Smell all around the appliance area for gas.  

Be sure to smell next to the floor because some gases 

(LP) are heavier than air  and will settle on the floor.  

If you do not smell gas  after this five-minute period , 

proceed with the lighting procedure.  

If you do smell 

gas,  do  not  proceed  with  the lighting procedure.   

Instead,  immediately  refer  to th e  What  to  Do  If 

You  Smell Gas Warnin g,  on the c over  of this 

manual.

NSTRUCTIONS

The gas control knobs are located at the top, right 

rear corner of the unit (

. 

Wait (5) five minutes to clear out any gas.  If you 

then smell gas, STOP! 

Smell all around the 

appliance area for gas. Be sure to smell next to 
the floor because some gases (LPG) are heavier 
than air and will settle on the floor. If you smell 
gas immediately follow the What To Do If You 
Smell Gas! warning on the cover of this Manual.

If you do not smell gas, go to the next step. 

5.  Turn gas control knob counterclockwise to 

“PILOT”. 

6.  Push in control knob all the way and hold in. 

(You should hear the clicking of the igniter in the 

firebox) Verify ignition of the pilot. Continue to 

hold the control knob in for about 20 seconds 

after the pilot is lit (ensures thermocouple is up to 

temperature).  Release the knob and it will pop 

back out. Pilot should remain lit.  If the pilot goes 

out, repeat the operation. 



If knob does not pop o ut when released, stop 

and  immediately  call a qualified service 

technician or gas supplier. 



If the pilot will not stay lit after several tries, 

turn the gas control knob “OFF” and call a 

qualified service technician or gas supplier.
