To provide correct pressure of the fuel supply to your stove, the tank outlet should be 

between 16” and 72” above the carburetor on the stove.  Do not exceed 72” above the 
carburetor as excessive head pressure could limit the carburetor’s ability to shut off fuel flow.  
Be sure the support system under the tank is safe and adequate as a full 300 gallon tank will 
weigh about 2000 lb. 
 

If you must install a tank below the stove, or above the recommended height, a lift pump 

and/or a level control valve must be fitted.  You will need to check local building codes 
regarding such installations. 
 
       

CONNECTIONS: 

 

There should be 2 valves on a typical installation: 1) a shut-off valve at the tank to allow 

service to any piping, or changing the main filter and  2) a shut-off valve close to the stove to be 
able to isolate the stove for any maintenance, and (if required by code) a fire valve right before 
the fuel pipe enters the building which would automatically shut off the oil supply in the 
unlikely event of the stove overheating.  Piping to the stove from the tank may be either steel or 
copper, but copper is preferred to prevent any rusting problems.  When making the fuel line 
connection with the copper line from the tank to the stove, it is best to have a gradual slope or 
“fall” on the line (i.e. no dips or kinks) so as to prevent any air bubbles or collection of dirt or 
other impurities.  A 3/8” diameter copper supply line is recommended and either compression 
type or flare type fitting may be used.  Finally, a good quality filter that also traps water should 
be placed at the tank to ensure a good, clean supply of oil to your stove.  The carburetor on the 
stove is equipped with a screen-type filter but it is not intended for use as the primary filter.

Lighting, carburetor adjustments, and draft stabilizer adjustments 

 

 

PRE-LIGHTING CHECKS: 

 

The installation should be inspected to ensure that the work is complete and the 

workmanship is satisfactory.  No stove should be lit if any part of the installation does not 
comply with the relevant standards and regulations. 
 

The oil tank should be examined to confirm there is a supply of the correct grade of oil, 

that a filter and a working isolation valve are fitted.  Having verified that the oil pipe work up to 
the stove is complete and that the fire valve (if used) is closed, the tank isolation valve should 
be opened and the pipe work inspected for leaks.  The pipe into the inlet of the metering valve 
should be uncoupled, the shut off valve opened and a minimum of one quart of oil collected 
into a suitable receptacle.  If dirt or water is present in this sample, additional oil should be 
allowed through the pipe work until it is free from contaminates.  The fuel pipe work should be 
reassembled and all connections checked for leaks and tightened as necessary. 
 

For 7” Burner Models: Laying on top of the catalyst inside your Oil Classic 7” burner 

model stove is a stainless steel top burn ring.  It is important that the ring be in the proper 
position.  It comes in the proper position from the factory.  Should the height of this ring 
change, it is easy to re-adjust by bending the three tabs that rest on the catalyst top up or 
down.  It is very important that the “cupped” part of the ring is facing up (as if it would hold 
water).  The stove will not burn properly if the ring is face down.  Locate the two continuous 
rows of air holes circling the burner top.  The top ring tabs should set on the catalyst top so 
that the outer edge of the ring comes out right between those two rows of air holes.

 

 

      

LIGHTING: 

 

Initial lighting should be undertaken by a qualified technician, with a suitable probe-

type manometer for checking the flue pressure.  Although adjusting the draft stabilizer by “feel”
