GENERAL
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:
1. 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.
a. Refer to drawing 1 and table 1 for details of terminal locations.
2. 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.
a. Refer to drawing 1 and table 1 for details of terminal locations.
b. 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.
c. 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.
d. 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.
3. The Clean Air Act for installations exceeding 333kW nett input.

TABLE 1WATER HEATER TERMINAL LOCATIONS
The table above should be used in conjunction with the following notes:
Distances shown ensure the Water Heaters will operate without problems under most conditions, these distances can be reduced in certain
circumstances
The above should be read in conjunction with the latest edition of BS5440-1 and IGEM UP10
For Water Heater installation above 333kW nett input the table above should not be used, these installations are covered by the clean air act and
must comply with its requirements in full, contact your local environmental health team for further guidance

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
considered. 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.
