Dear Lucy
PA 18/001100/GB & 18/01101/CON – Installation of boiler flue, window alterations and replacement of kitchen flue, The George Hotel, Castletown, IM9 1LG
Further to your letter of 30 January 2019 I can confirm that the siting and specification of both flues was carefully considered at the time of installation.
As you know the elements of work in question formed part of an extensive refurbishment which constitutes a significant investment by Heron & Brearley aimed at the need to breathe life back into the building and the area as a whole.
As previously stated the Kitchen canopy extract flue is simply a replacement of an existing extract flue to meet current standards,
As affirmed in Star Services Ltd’s technical appraisal, the design and installation of the system has been carried out to meet the requirements of the Gas Safety Regulations, Health and Safety Regulations and Heating and Ventilation Contractors Association’s DW 172 specification for Kitchen Ventilation Systems, with the new flue simply being 100mm larger than the one it replaces.
The siting of the flue on the rear of the building directly responds to the location of the Kitchen, the structural layout of the building and the need for it being accessible for removal for cleaning on a regular basis for fire safety reasons, and its vertical discharge in lieu of the original downward discharge is the only way to keep it within the regulations in terms of eliminating smells in the surrounding area where opening windows are present.
This upgrade of the flue was an integral part of the Kitchen refurbishment. As stated in the conservation officer's report none of the original features of the building have been affected by its replacement and from a health and safety point of view, in terms of odour control, its upgrade is betterment to the conservation area as a whole.
As suggested by the conservation officer, we can confirm that Heron and Brearley will accept a planning condition that requires the flue to be removed upon any redundancy of the Kitchen from this location with suitable window replacement the details of which are to be agreed with yourselves as and when the need arises. In the meantime, if considered necessary, Heron and Brearley can arrange for the flue as it stands to be painted cream to match the building when it is next removed for cleaning.
With regard to the boiler flue, as affirmed by Industrial & Domestic Plumbing and Heating Ltd under cover of their letter dated 11 February as attached the location of the boiler was chosen because it was the only suitable location available that was compliant with gas regulations. IGM/UP2/10 ED4 and BS6644 Boiler flue termination, IGEM/UP21A – Tightness testing and IGEM/UP2/2 – Pipe work all refer. The flue discharges vertically as a horizontal discharge would not have been within the regulations due to distances from an internal corner and openings, the distances for commercial installations being greater than that of a domestic gas boiler. The existing boiler room was internal and although acceptable for oil installations, lack of ventilation precluded the gas boiler being sited in the previous boiler location. The boiler is now close to the remainder of the extant plant room equipment with natural ventilation having now been provided by means of the window being replaced by a louvre.
In overall terms the change from oil to gas is betterment to the conservation area as it has allowed the oil storage compound to the rear of the building to be removed from its intrusion into the beer garden.
Whilst these minor elements of change to the very extensive refurbishment project as approved under PA 17/01332/GB have given rise to some visual impact, no third party concerns have been raised and no original features of the registered building have been affected by the works in question.
Rather than being detrimental to the registered building and the conservation area as a whole the extensive refurbishment undertaken at The George represents an improvement on the previous situation, a matter borne out by its increased popularity with all the benefits that this brings to the area as a whole and in particular to the long term viability of this registered building remaining as a pub and hotel.
Yours sincerely,

Good morning Helen
With reference to the George extract system I have enclosed the table on how it was worked out for sizing etc. This was sent with the previous email.
These works were done in accordance with gas safe regulations, H&S and DW172.
The exit of the ductwork is in the same place as it was before the refit. The size is 100mm bigger. The only difference being the vertical discharge unit fitted which was done to appease the surrounding population from smells etc. from the now bigger kitchen this was the remit was given to us
With opening windows in the area this was the only way to do it to keep within the regulations
Due also to the structural layout of the building the exit point used is the only one suitable for this purpose
I trust this helps
Regards
Nigel
The extract system installed at the George Hotel, Castletown has been done in the configuration that is here for the following reasons. Calculations for the air removal and associated fumes/products of combustion from the cooking appliances. Heat build up from them together with the safety and comfort of the staff working within the kitchen.
It is also done in order to comply with current Gas Safe Regulations and Health & Safety Standards, consequently the increase in size as regulations have changed since the last kitchen was installed. The whole installation is calculated as a result of these requirements and our workings out for this are as follows:
Total flow rate of 1.887 m3/sec
An extract fan capable of extracting 1.887 m3/sec from kitchen. At this flow rate, specification for correct extraction should need no less than 500 mm extract bore and a fan to suit (1.887 m3/sec)

Dear Helen
Thank you for your correspondence regarding the location of the new vertical flue installation at the above premises.
The location of the boiler was chosen because it was the only suitable location available that was compliant with gas regulations.
IGEM/UP2/10 ED 4 and BS6644 Boiler flue termination IGEM/UP2/1A – Tightness testing IGEM/UP2/2 – Pipe work
Similarly the flue discharged vertically as a horizontal discharge would not have been within the regulations due to distances from an internal corner and openings. This is a commercial installation which is classified as 70kw and above, the distances are greater than a domestic gas boiler.
The existing boiler room was internal and whilst acceptable for oil lack of ventilation precluded the gas boiler being sited.
Please let me know if you require and supporting documentation
Kind regards
Steve Thompson
