GENERAL

1.7 Intended use

This boiler must only be used for the purpose specified by the
manufacturer and for which it is designed.
The RTC-80 can be operated with gas, oil, and combination burn-
ers. For a list of the approved burners, see specific paragraph in
this manual.
A variety of alternate fuels such as biodiesel, jet fuel, etc may also
be utilized (contact R engineering for applicability).
The boiler can be operated with an aquastat and other control
systems.
The manufacturer declines all responsibility, contractual or other,
for damage to property or injury to persons or animals caused by
improper installation, adjustment, maintenance or use.

1.9 Regulations and guidelines

1.9.1 National regulation

The heating system must comply with the requirements of the rel-
evant regulatory authorities or otherwise of the National Fuel Gas
Code, ANSI Z 223.1.
If specified by the relevant regulatory authorities, the heating sys-
tem must comply with the regulations of the Standard for Controls
and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.
Carbon monoxide detectors must be installed as specified by the
local regulations. The boiler must be serviced annually.

1.9.2 Compliance with standards and regulations

Installation of the boiler must comply with all applicable codes
and regulations imposed by the national, federal or local author-
ities and bodies. If no specific requirements are defined, in the
USA, the boiler must comply with the latest edition of the National
Fuel Gas Code ANSI Z223.1/NFPA 54.
Where required by local regulations, the system must comply with
the American Society of Mechanical Engineers Safety Code for Con-
trols and Safety Devices for Automatically Fired Boilers (ASME CSD-
1).

WARNING: Risk of fatal injury from explosion of flammable
gases.
− Installation, connection of the fuel supply and flue pipe,
commissioning, connection of the electrical power supply,
servicing and repair may only be carried out by an autho-
rized heating engineer.
− Any work on gas piping components may only be carried
out by an authorized gas installer.
The local regulations regarding minimum pressure detectors,
maximum relief valves and low water safety cutouts must be ob-
served. Installation and operation must comply with the device
manufacturer's technical documentation.
We recommend fitting an 80 mesh dirt filter externally to the
boiler return to prevent contamination of the boiler by the water
source.
Leak test
A leak test must be carried out on the hydronic heating system.
The testing pressure is based on the normal operating pressure of
the heating system and should be 1.3 times that pressure, and in
any case no less than 14 psi (1 bar).

1.9.3 Additional regulations for installations in the
Commonwealth of Massachusetts
a) For all side wall horizontally vented gas fueled equipment in-
stalled in every dwelling, building or structure used in whole or in
part for residential purposes, including those owned or operated
by the Commonwealth and where the side wall exhaust vent ter-
mination is less than seven (7) feet above finished grade in the
area of the venting, including but not limited to decks and porch-
es, the following requirements shall be satisfied:
INSTALLATION OF CARBON MONOXIDE DETECTORS: At the time of in-
stallation of the side wall horizontal vented gas fueled equip-
ment, the installing plumber or gasfitter shall observe that a hard
wired carbon monoxide detector with an alarm and battery back-
up is installed on the floor level where the gas equipment is to
be installed. In addition, the installing plumber or gasfitter shall
observe that a battery operated or hard wired carbon monoxide
detector with an alarm is installed on each additional level of the
dwelling, building or structure served by the side wall horizontal
vented gas fueled equipment. It shall be the responsibility of the
property owner to secure the services of qualified licensed pro-
fessionals for the installation of hard wired carbon monoxide de-
tectors.
− In the event that the side wall horizontally vented gas fu-
eled equipment is installed in a crawl space or an attic, the
hard wired carbon monoxide detector with alarm and bat-
tery back-up may be installed on the next adjacent floor
level.
− In the event that the requirements of this subdivision can-
not be met at the time of completion of installation, the
owner shall have a period of thirty (30) days to comply with
the above requirements; provided, however, that during
said thirty (30) day period, a battery operated carbon mon-
oxide detector with an alarm shall be installed.
