TECHNICAL SPECIFICATIONS
GENERAL
Burner and Gas Train selections for Natural Gas applications are based on standard design requirements (as stated in IGE/UP/2) of 20mbar gas pressure available at the appliance under max flow conditions. If this pressure is not available, or the available gas pressure is higher, or for alternative fuel types – please consult your sales contact for alternative matching.

BURNER MATCHING OPTIONS
- Modulating and Low NOx options are available; please contact us for full details. Oil burners would be subject to confirmation that the fuel supply was a suitable type/grade.
- Burner matching for LPG operation by special request.
SUGGESTED ENGINEERING SPECIFICATION
The Suggested Engineering Specification is wording designed for specifiers to copy and paste into their specifications to ensure the inclusion of Ideal Heating commercial boilers.
OVERVIEW
The boiler must be a fully automatically controlled, floor-standing condensing
boiler with a triple flue pass stainless steel heat exchanger. While they are
designed primarily for central heating purposes, in conjunction with a
suitable storage cylinder they can also be used to produce domestic hot water
on an indirect fully pumped sealed water system.
All parts that come into contact with the combustion gases are made from
titanium-stabilised stainless steel to ensure maximum resistance to the
corrosive action of acid condensation.
The boiler must incorporate two return water connections to facilitate
multiple applications e.g. CH & DHW and enable the optimum operating
efficiency to be achieved.
The boilers must be designed to operate with Natural Gas, LPG or Oil (delete
as required) using pressure-jet or premixed burners. The burner specification
will enable the choice of 2-stage, Modulating, Low NOx and Ultra Low NOx
operation.
CONTROLS
The boiler control options must be selected at the time of purchase:
- Two stage burner
- Modulating burner
- BMS 0-10V
- Oil & dual fuel
The boiler must include control features enabling set point adjustment,
heating circuit control of one constant temperature, one variable temperature
and one DHW circuit and safety lock out parameters including fault diagnosis
for both boiler and external components such as sensors or pumps.
Boiler capabilities must include, with the use of external components, frost
protection, weather or room compensation and system pump control.
FLUE
The condensing boilers must be suitable for use with an open-flued application
in B23 configuration. The B23P configuration can only be used with a premix
gas burner.
HYDRAULIC
The condensing boiler must be suitable for connection to a fully pumped sealed
water system. All hydraulic connections including flow return and condensate
drain must be located on the bottom or rear of the boiler. The boiler must
have a maximum operating pressure of 6 bar and be suitable for heating and
indirect hot water systems.
DIMENSIONS
The condensing boiler must fit within maximum permitted floor space of 0.97m²
(150 and 210kW models)/1.23m² (270 and 350kW models)/1.47m² (450 and 900kW
models)/2.03m² (800 and 1000kW models)/2.40m² (1250kW model)/2.67m² (1450kW
model)/6.34m² (1750kW model)/7.04m² (2100kW model)/8.19m² (2700kW)
model/9.00m² (3000kW model).
MOUNTING / POSITIONING
The condensing boilers will be floor-standing.
EFFICIENCY
The condensing boilers are capable of high seasonal efficiencies with a
minimum requirement of 95.8% (Part L Vol.2 2022) and low NOx emissions between
43 – 65mg/kWh (47 – 70mg/Nm³) depending on boiler model, using Low NOx Natural
Gas burner.
APPROVALS
The manufacturer must be ISO 9001 accredited

| BOILER MODEL | MIN FLOW (L/H) |
|---|---|
| 150 | 1,700 |
| 210 | 2,400 |
| 270 | 3,100 |
| 350 | 4,000 |
| 450 | 5,100 |
| 600 | 6,800 |
| 800 | 9,100 |
