provided, however, that during said thirty (30) day period, a battery operated carbon monoxide detector with an alarm be installed.

2.Approved Carbon Monoxide Detectors

Each carbon monoxide detector shall comply with NFPA 720 and be ANSI/UL 2034 listed and IAS certified.

3.Signage

A metal or plastic identification plate shall be permanently mounted to the exterior of the building at a minimum height of eight (8) feet above grade directly in line with the exhaust vent terminal for horizontally vented gas fueled heating appliance or equipment. The sign shall read, in print no less than

one-half (1/2) inch in size: "GAS VENT DI-

RECTLY BELOW, KEEP CLEAR OF ALL OBSTRUCTIONS".

4.Inspection

The state or local gas inspector of the side-wall horizontally vented gas fueled appliance shall not approve the installation unless, upon inspection, the inspector observes carbon monoxide detectors and signage installed in accordance with the provisions of 248 CMR 5.08(2)(a) 1-4.

3.4 Common Vent Test

NOTE: This section does not describe a method for common venting Brute Elite units. It describes what must be done when a unit is removed from a common vent system. Brute Elite units require special vent systems and fans for common vent. Contact the factory if you have questions about common venting Brute Elite units.

When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the appliances remaining connected to it.

At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.

1.Seal any unused openings in the common venting system.

2.Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
