TECHNICAL - Replace Parkray Chiltern & Cumbria Glass

Information about replacing a Parkray Chiltern or Cumbria stove glass.


 
The below information relates to a Solid Fuel Stove only. (NOT Gas Appliances).
 
When replacing the door glass on a Parkray Chiltern or Cumbria stove, we recommend that the door is removed from the appliance.  Soak the 'glass retaining bolts/studs' overnight with releasing oil, this makes them easier to remove. Be very careful NOT to twist off the bolts/studs; should this happen the holes should be redrilled and tapped and new bolts used. Be sure not to alter the door adjustment screws.
 
To remove the door:- remove hinge pins – 2 per door. There are 8 bolts on each door (4 to remove the inner door and the other 4 are just to adjust the door so that it closes correctly).
 
After removing the damaged glass and old seals, scrape or chisel off any rust which has accumulated.   (It is important that the glass can sit flush against a clean door surface - so clean well).  Then treat the area with a RUST preventative, once this is dry you can then paint the frame with a heat resistant paint which helps to retard the rust, when dry fit the glass and seals. The best seal we have found is Self Adhesive Glass Sealing Ladder Tape as the “U” shaped sealing channels are no longer manufactured!
 
NOTE: IT IS IMPORTANT TO TOTALLY CLEAN & TREAT THE RUST FROM THE AREA WHERE THE GLASS SITS / IS AGAINST THE DOOR.  UNEVEN SURFACES WILL CAUSE CRACKING WHEN THE FIRE TEMPERATURE IS INCREASED (AS PARTS OF THE APPLIANCE EXPAND).  GLASSES CAN ALSO CRACK IN SUMMER WHEN THE FIRE IS NOT IN USE (AS THE RUST EXPANDS).  DO NOT OVER TIGHTEN THE GLASS WHEN REFITTING AS THIS WILL NOT ALLOW ROOM FOR METAL EXPANSION.
 
Grease the bolts/studs prior to refitting with high temperature grease, it will make them easier to remove in the future.
 
Lay the Glass on the door (with Ladder Rope already stuck to the Glass) and refit the retaining bolts/studs.  It is important that they are tightened down evenly but not over-tightened as this may well crack the glass when the metal of the door expands with heat from the fire.
 

 
Health Warning: It is important when refering to our guidelines that you work / read them in conjunction with the instruction manual for the stove.  This information should not be seen as advise for your particular stove.  It is just a 'general' guideline of how we would change a Stove Glass in our Workshop.  We recommend that you use a trained / qualified engineer to replace Stove Glasses.  Fireparts.com offer a Glass Replacement Service (collection and return to your home) if you would like us to refit your glass.
