Liner Pack & Stove Kits

Direct Stoves - Stove Fitting Kits*
What's included in the fitting kit
  • 1. Black stove pipe.
  • 2. A registration plate is used to seal the chimney opening off from the room preventing dust, soot, dirt and debris falling down the chimney. It also helps to prevent a draft coming down the chimney. We supply a standard 800mm x 400mm galvanised steel register plate with all our stoves. You will simply need to cut the plate to size to fit into your chimney opening.
  • 3. We also provide you with a single stove glove that you can use for stoking the fire and adding wood without the risk of personal injury.

Q & A

Can the boiler stove be plumbed into a combi boiler and would I have to put a water tank in for hot water
Question by: Adrian on 20 Nov 2022, 19:40

Thank you for your enquiry.

This can be used in a combi-boiler. If you are plumbing the boiler to it you would need a thermal store.

Hope this helps.

If you have anymore enquiries please email [email protected]

Delivery Info

Free 1 Man Delivery – For Full Details Please See Delivery Information

Our "Free Delivery" is a one-man service. The goods will arrive on a lorry that is about the size of a fire engine. (Please let us know in advance if you have restricted access or other local issues that could affect delivery).

The lorry has a tail lift that allows the driver to get the item(s) off the vehicle. The order will be packed and secured onto a pallet and the driver will have a pallet truck. He'll be able to wheel this as close as possible to your property. The pallet truck can only be wheeled over a finished surface so it's not possible to wheel it over a gravelled drive, steps, steep slopes for example. The pallets are normally about 1m wide so this is the minimum width gate they can fit through. Please note that the driver is not insured to unpack or carry the item(s) into your house.

Fitting Kits and Liner Packs might arrive separately by courier delivery on the same day unless specified/requested in advance. An email confirmation will be sent if this is the case.

If the goods are showing 48hr delivery, then this is the quickest time we're able to deliver these items (We do not deliver at weekends). You'll be asked to select a delivery date when purchasing the goods. Please note that if you live offshore these dates do not apply as it will take us slightly longer to get the goods to you and we will contact you directly.

Please note that it is an all-day delivery service which is generally from 9 am – 6 pm Monday to Friday. Delivery Depots, if they have the facility, will text in advance but as the vans do multiple runs a day you might not receive a text until the afternoon if this service is available.

Due to current pallet network pressures mainly due to driver shortages we cannot guarantee delivery on your chosen day but will do our best to communicate this as soon as we are made aware by the carriers.
