Changing The Glass On Your Stove

One of my favourite things about a stove is the fact that you can maintain the cosy ambience that you get from an open fire. From time to time however, accidents can happen. Many of us will find that we need to replace cracked, or cloudy glass. Luckily changing the glass on your stove is relatively straight forward and simple. Cloudy glass is often caused by burning fuel with a high moisture content, or paper, cardboard or plastics that contain chemicals. Only ever burn trusted fuel in your stove. One of the main causes for cracked glass is overloading the fire box. A stray log can crack the glass as the door is closed, or as logs shift during a burn they can fall against the door. Being careful loading fuel and cleaning your glass regularly will help to ensure that your glass will last for years.

In this handy guide, ‘Changing The Glass On Your Stove’, we will walk you through the simple process of removing your old glass and then fitting the new glass. This is a very simple process and should take no longer than 30 minutes. You will need, a 6mm spanner. A pair of tough gloves for handling broken glass. 12mm x 3mm self-adhesive stove rope. High temperature silicone adhesive and the replacement stove glass. All these materials should be easily obtained from your local Boru Stoves Stockist. If you have any problems finding these parts you can contact Boru Stoves directly for assistance. Remember to always use genuine Boru Stoves parts to ensure you do not invalidate your warranty.

1. Remove The Door Of Your Stove

You should begin by removing the door of your stove. This will make removing the old glass and fitting the new glass much easier. Wearing tough gloves, open the door and ensure that any loose pieces of glass are removed before removing your door. The door of your Boru Stove can then be removed very easily by lifting it off the hinges [Fig 1] [Fig 2] [Fig 3]. Ensure you have a suitable surface to place the door on to work without damaging it.

2. Remove The Broken Glass

Using your 6mm spanner, you should remove the nuts holding the clips in place [Fig 4]. A lubricant such as WD-40 can help to loosen sticking nuts, then fully remove the clips. You should then be able to safely remove any remaining glass [Fig 5]. You should now remove the existing rope seal that may be left behind after removing the glass. Once removed, be sure clean the area where the old seal was placed to remove any dust or debris [Fig 6].

3. Apply New Rope Seal

You are now ready to apply the new rope seal. Using a 12mm x 3mm self adhesive high temperature rope seal, begin in the bottom right hand corner [Fig 7]. Be sure to extend the seal beyond the edge of the opening by around 12mm [Fig 8], this will allow you to create a snug seal with the other end of the rope, ensuring you have an airtight stove. Work your way around the rest of the door taking time to follow and contours or curves that the door might have [Fig 9]. Finally, if needed, trim the rope so that the two ends meet and create a snug seal. You should place your glass on the seal and make sure that the seal is within the edge of the glass and that there are no points where the glass will not be sealed against the stove door. Once you have made sure of this, you can put the glass to one side.

4. Fitting The New Glass

When the seal is in place we need to apply a small amount of high temperature silicone adhesive. Apply a small amount onto the entire length of rope seal that you have just fitted [Fig 10]. You can then sit the glass into place, be careful to align your glass correctly before making contact with the prepared seal. Apply a very small amount of pressure around the edges of the glass to ensure a tight seal with the adhesive [Fig 11]. You should now replace your clips, if any clips or nuts are damaged or missing, you should be able to obtain these from a Boru Stoves Stockist. Once the clips are in place, you should add a washer and then tighten the nut into place [Fig 12]. The nuts should be finger tightened only. Be very careful not to over tighten the nuts, if in doubt, err on the side of caution. The glass is fragile and concentrated pressure can easily crack the glass, the glass is heat resistant, not impact resistant. With the glass now fitted you can hang the door back onto your stove.

The glass on a stove is a part that is commonly replaced, similar to the windscreen on a car. Many factors can effect the life of glass in a stove, and accidents do happen.
