GENERAL
CERTIFIED FLUE SYSTEMS
Lochinvar Water Heaters are certified for use on the following flue categories:
| Installation type | Category | Description |
|---|
B23
|
Open flue
| An appliance intended to be connected to a flue that evacuates the products
of combustion to the outside of the room containing the appliance. The
combustion air is drawn directly from the room.
C13| Closed Flue| An appliance connected to either a concentric or twin-
pipe flue system with a Horizontal flue terminal. Both the air inlet and flue
exhaust must be in the same pressure zone.
C33| Closed Flue| An appliance connected to either a concentric or twin-
pipe flue system with a Vertical flue terminal. Both the air inlet and flue
exhaust must be in the same pressure zone.
C43
|
Closed Flue
| An appliance connected to a common air inlet and flue exhaust system, which
is designed for more than one appliance. This common system has a single air
inlet and flue exhaust and is part of the building not the appliance.
C53| Closed Flue| An appliance connected to a twin-pipe flue system with
a Horizontal or Vertical flue terminal. Both air inlet and flue exhaust may be
in different pressure zones.
C63
|
Closed Flue
| An appliance intended to be connected to a separately approved and marketed system for the supply of combustion air and discharge of combustion products (i.e. other than that supplied by the water heater manufacturer).
All installations should comply with the requirements of:
- For appliances up to 70kW net input- BS5440-1:2008- Flueing and ventilation for gas appliances of rated input not exceeding 70 kW net (1st, 2nd and 3rd family gases). Specification for installation of gas appliances to chimneys and for maintenance of chimneys.
- Refer to drawing 1 and table 1 for details of terminal locations.
- For appliances over 70kW net input- IGEM/UP/10 Edition 4 +A: 2016 – Installation of flued gas appliances in industrial and commercial premises, specific attention should be paid to the following sections.
- Refer to drawing 1 and table 1 for details of terminal locations.
- Horizontal terminations shall be located according to the minimum distances given in table 1, and subject to the risk assessment criteria shown in table 2.
- Horizontal flue terminations (other than for fan dilution systems) must not be installed for any single appliance or group of appliances with a total nett input exceeding 333kW net heat input.
- For any single appliance or group of appliances with a total net heat input exceeding 333 kW, the general requirements of IGEM/UP/10 Edition 4 +A: 2016 shall apply and approval must be sought from the Local Authority prior to commencement of the installation.
- The Clean Air Act for installations exceeding 333kW nett input.

multiple Water Heater installation above 333kW nett input are covered by the clean air act and must comply with its requirements
see UP10 figure 7 for full clarification
TABLE 2 RISK ASSESMENT
The table below is an excerpt from IGEMUP10 and should be used in conjunction
with that document
Further to the requirements in IGEM/UP/10 Edition 4 +A: 2016 Section 8 under clause 8.7.3.3 and Figure 7 the following risk assessment gives guidance for the positioning of horizontal flues. This form should be completed before work commences and undertaken by a person who is competent to undertake the risk assessment.

COMMON FLUE SYSTEMS
Any installations using flue type C63 must be designed and installed in compliance with any local Building or planning regulations, but as these systems use a flue system not supplied by Lochinvar, Lochinvar cannot comment / advise or provide support on the design of this type of flue system. To design such a flue system, the installer/contractor must consult a specialist flue supplier who will be responsible for the design and installation of the separate flue system. When designing the type C63 flue system, the instructions in the Installation Manual, provided with the water heater, must be taken into account. Lochinvar will provide pressure loss figures for the specific units, but other than that, Lochinvar cannot provide support on Common Flue requests because flue certification is limited to the certified categories in the table on page 2. Lochinvar cannot accept any responsibility for Flue system design.
