Stretton Insert Stove This appliance is hot while in operation and retains its heat for a long period of time after use. Children, aged or infirm persons should be supervised at all times and should not be allowed to touch the hot working surfaces while in use or until the appliance has thoroughly cooled. When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be used to prevent accidental contact with the stove.

INSERT STOVE INSTALLATION & OPERATING INSTRUCTIONS PRE-INSTALLATION NOTE: Please note that it is a legal requirement under England & Wales Building Regulations that the installation of the stove is either carried out under Local Authority Building Control approval or is installed by a Competent Person registered with a Government approved Competent Persons Scheme. HETAS Ltd operate such a Scheme and a listing of their Registered Competent Persons can be found on their website at www.hetas.co.uk.
ALL FLUE INSTALLATIONS ARE THE RESPONSIBILITY OF THE INSTALLER Fig 2 Any existing chimney must be clear of obstruction and have been swept clean immediately before installation of the stove. If the stove is fitted in place of an open fire then the chimney should be swept one month after installation to clear any soot falls which may have occurred due to the difference in combustion between the stove and the open fire.
Fig 5 Fig 4 Step 8 Then using the M6 screws secure the stove to the convection chamber. Push the insert stove against the fireplace before fully tightening these bolts. Step 4 Drop the flexi flue liner down through the chimney, connect the 5 - 6” flue pipe adaptor and the rigid pipe section to the liner (see Fig.5). Step 9 Push the rigid pipe back up through the flue outlet and fix the flue spigot into position using the M8 nuts provided.

Optional Ashlip To insert the side liner bring the casting carefully towards the opening, the bottom edge needs to go towards the side it will fit to and the top edge goes to the centre of the stove. With the casting tilted like this, then the casting should pass through the opening in the front. 6.
9. Fire Fence When calculating combustion air requirements for this appliance use the following equation: 550mm2 per each kW of rated output above 5 kW should be provided, where a flue draught stabiliser is used the total free area shall be increased by 300mm2 for each kW of rated output. If there is another appliance using air fitted in the same or adjacent room, it will be necessary to provide an additional air supply.
Fig.10 COMMISSIONING & HANDOVER On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, when a small fire may be lit and checked to ensure the smoke and fumes are taken from the stove up the chimney and emitted safely to the atmosphere. Do not run at full output for at least 24 hours. On completion of the installation and commissioning ensure that the operating instructions for the stove are left with the customer.

PRIMARY AIR CONTROL SPIN VALVE Fig.15 When burning manufactured smokeless fuels, the spin valve located near the bottom of the door, controls the primary air supply to the stove. For maximum heat output and burn rate rotate the spin valve fully in an anti-clockwise direction. For a minimum burn rate rotate the spin valve fully in a clockwise direction until fully closed. For nominal heat output the spin wheel will need to be open about 2 turns depending on the draught conditions of the chimney.
Fig.16 Fig.17 MAINTENANCE SLOW BURNING CREOSOTE - Formation and Need for Removal When some fuels are burned slowly, they produce tar and other organic vapours, which combine with expelled moisture to form creosote. The creosote vapours condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited creosote makes an extremely hot fire.
5. Never allow a build up of ashes in the ash pan, as this may cause the grate to burn out prematurely. WARNING NOTE Properly installed, operated and maintained the stove will not emit fumes into the dwelling. Occasional fumes from de-ashing and re-fuelling may occur. However, persistent fume emission is potentially dangerous and must not be tolerated. If fume emission does persist, then the following immediate action should be taken: 6.
4. A plan to deal with a chimney fire as follows: LIGHTING a. b. Before lighting the stove check with the installer that the installation work and commissioning checks described in the installation instructions have been carried out correctly and that the chimney has been swept clean, is sound and free from any obstructions. As part of the stoves commissioning and handover the installer should demonstrate how to operate the stove correctly. c. d. Notify the fire department.
